RapidXen VPS

RapidXen

Ordered a RapidXen VPS yesterday to setup a LAMP server, and for testing some virtualization manager for my other server. Just got a mail from the admin there saying that my account has been provosioned. Yahooooo! ^_^ But, I mistakenly shutted down the server with "shutdown -h now" command, it should be "shutdown -r now". Alamak! Tersilap! Haha... I'm mailing the admin (William Pitcock) asking how I could start up the server... aiseyyy...

Akasaki Research Center 8th Symposium

Akasaki Research Center Website

Attended Akasaki Research Center 8th Symposium at IB Building, Nagoya University today (Nov 20th, 2008). The event started at 10:30 until 17:30, with speakers that are among professors and associate professors from universities around Japan, France and Sweeden. I went there together with Dr Chin, Pum and Shu. The weather was pretty cool since the morning, but we went there by bicycle as planned (even though I thought I just want to go there by subway... but Pum came to my place by bicycle, so it'd be interesting too to go together by bicycle, hehe ^_^)

I've seen some of the contents in the talks in another meeting I attended before, but I'm totally impressed with presentation by Prof Noda of Kyoto University! He's doing research on photonic crystal, and his approach to GaN is pretty cool! Maybe I could try his approach photonic crystal on my InGaN on Si laser diode that I'm working with. It would take another 2 years though... but it's good for the continuity of my research in the future, probably when I have my own MOCVD in my own laboratory in Malaysia. I really need a MOCVD to realize my future research! It's not good to speculate much what I'm gonna do in the future as this is a public blog, but it's worth to note. His talk on PC (photonic-crystal) was really easy to understand, not like some other professors who just show plotted graphs and datas on their slide, without really explaining to the audiences what the basis and real-world facts.

The other talk that attracted my interest is by B. Monemar who explained about p-type doping (by Mg) in GaN. The good thing is, this is what I'm looking since half a year before! His PL peaks from Mg-doped GaN samples were pretty much identical with what I got in my (*****) samples! That's impressive! I'll read all his papers in the coming weekend. He's answered most the questions in my p-doped samples... haha!

There're also some other good presentations, about InN, etc, that I believe a pretty good achievements. However, there're presentations like Moth-Eye surface LED that I already saw before, at Japan-China-India Workshop held at my university. The GaN growth on Si substrate presented by a student in Sawaki Group (Nagoya Univ) was also a blend of old and new results. I saw part of the content at Tokai Region Nitride Research Meeting last year, and there was talk about research on AlN growth by Mie university group which I saw during the same meeting last month (at Meijo Univ).

Okay, that's all. Bye ^_^

alan - 心・戰 Xin Zhan ~Red Cliff~ complete music video (with English translation)

Watched Red Cliff movie with Mr Shimada last night. Really like this ending theme... the music is so soothing :)

Misha Omar - Dedebu Cinta

An exhilarating voice of Misha Omar, one of my favorite Malaysian pop singer.

Warisan - Anak Kecil Main Api

A song that brings my heart to the past...

Some breath-taking view photos of my hometown city...

Owhh... I could spot my house, the nearby sport stadium, airport, and my playground... haha! Really miss this place.


A Malaysia Airlines B747 jumbo plane during landing at Sultan Mahmud Airport, Kuala Terengganu. See the stadium in the background? I pass that place everyday to go to my school last 15 years ago :) (at that time, there's not even a single building on that ex-paddy field area).

Mid-term Presentaton

Finished my mid-term presentation for my laboratory in the evening... :) This is the first time I did it in English. Usually, I did it in Japanese, but today, Josephine and Pum did it in English, so ME TOO! I'm a foreign student, not a Japanese! Doing it in English is far more easier, but the problem is we cannot expect questions from the Japanese students, that's why all my previous presentation in the laboratory were made in Japanese.

About the presentation... hmm... just showing my old data. Six-month-old data. So, Even egawa sensei didn't ask me because he already knows what the content is. My new data is still very confidential at the moment. Probably, Egawa is the first guy who will see it, haha... I've gave him some hint about it a couple of days ago. So, he expect me to show him the data. Haha... most part of the analysis has finished, just a few corrections that I'm working with. Insya'ALLAH, at least another paper for this data alone... Insya'ALLAH :)

Okay, have to get some sleep. So tired because as usual, had seminar after the presentation, had some shopping at Jusco after that, and had hot-pot with my friend at home... haha! Too much activities in a single day... too tired.

See ya'!

YATTA!!!

Ha ha...! Really like this one! So simple (maybe stupid), but it's very interesting!

Nagoya Hari Raya Party

Today, wa had Malaysian Hari Raya party at International Students House Lobby, Nagoya Institute of Technology. The event was partipated by Malaysian communities living around Nagoya and Toyota city. We had a lot of Malay dishes! Haha... really enjoyed it! I'll post more pictures soon ^-^

Happy Hari Raya to All

Maybe it's still not too late to wish Happy Hari Raya Aidilfitri to all Muslims around the globe. I don't have much time to spend time blogging here these days, but I really miss this site. Called my family back home in Malaysia, but seems everybody's too tired with the celebration and open house... so nobody wanted to speak with me... hmmm. Okay, till then. Wassalam.

Turn off indexing and speed up Windows XP

If you don't use Windows XP's built-in search often (like every day), disabling indexing can significantly speed up your PC.

By default Windows XP indexes files on your hard drive and stores them in memory to speed up its' built-in search. But if you rarely use Windows search, turn off indexing to free up memory and CPU horsepower for the files and applications you actually do use. A few simple how-to steps after the jump.

To turn off indexing:

1. Open up "My Computer."
2. Right-click on your hard drive (usually "C:") and choose "Properties."
3. Uncheck the box at the bottom that reads "Allow Indexing Service to..."
4. Click OK, and files will be removed from memory. This removal may take a few minutes to complete.

To disable the indexing service:

1. In the "Start" menu, choose "Run."
2. Type "services.msc" and press Enter.
3. Scroll-down to "Indexing Service" and double-click it.
4. If the service status is "Running", then stop it by pressing the "Stop" button.
5. To make sure this service doesn't run again, under "Startup Type:", choose "Disabled."

Windows search will still work if you perform these steps, but it will work more slowly than if indexing was enabled.

Haha... proud to be Malaysian!

PETRONAS CHINESE NEW YEAR 2008 AD, REUNION DINNER

I like this one, from Petronas Malaysia.

Finished temperature-dependence photoluminescence (PL) measurements...

So tired... finally finished TD-PL just now, from 5K to 300K (10K increment for 5K-100K & 20K increment for 100K-300K). There's 5 samples to measure... actually, it's not the sample which make it hard, but the temperature increment which make it very boring measurement. At first, I had to put my samples into a cryostat, cools the cryostat using liquid Helium until it reaches 5K, and increase the temperature according to the measurement parameter using a heater. And, there's a lot of waiting to get the temperature stabilized, before doing the photoluminescence (PL) measurement.

What makes it a tiring measurement is... there was problem with the diffusion pump when I vacuum the cryostat last night (after putting my sample in). Even after waiting for 2 hours, the pressure still at 2 x 10^(-2) Pa. It should be around 1 x 10^(-4) Pa after 40 minutes pumping...

Then, when it reached 5K this morning, I found that the He-Cd (helium-cadmium) laser [used to excite electron in MQW (multi-quantum-well) structure of my sample] didn't reflected properly / passing properly through mirror / lenses on the optical configuration. The worse thing is I found 2 laser spot on my sample, even though there's only 1 laser used in the configuration. I think somebody has accidentally touched the mirror/lenses on the optical table... I was soooooooooo ANGRY!!! But, who? Arghhh...

Fortunately, I fixed the mirror direction on the optical table to get 1 laser spot on my sample... fortunately... seems like it's ok. Dr. Ishikawa must be sooo angry if he found that thing happened again. Everybody who do PL must be angry if he/she found the laser is reflected to different direction... it's normal thing in this field. But, who did it? Hmm... no idea... maybe those guys... (no more comments)

Okay, I've to go home... so tired. I've to spend many hours to analyze the PL data...

Just hoping I could sleep well tonight... Insya'Allah.

~~~ So happy to see a mail from Chongqing in my mailbox just now :) ~~~

Yet another ω-2θ scan...

Doing omega-2theta scan for my MQW sample on GaN substrate. Got the BEST result I've ever collected for my MQW structure! And hope this is among the best result in the world! Alhamdulillah... berkat bulan Ramadhan.

Japan Applied Physics Society Fall Meeting

Japan Applied Physics Society Fall Meeting is being held at Chubu University, not so far from Nagoya. I also went there to listen for special symposium on GaN research today. The speakers are Prof. Akasaki (Meijo Univ.), Prof. Amano (Meijyo Univ.), Prof. Shuji Nakamura (Univ. of California at Santa Barbara), and a guy from Toyoda Gosei (sorry, not remember his name) who is managing opto-electronics department there.

Frankly speaking, I've read/seen most of the contents in their presentations, but listening to their presentations gave me a perspective that they've devoted all their life for what they've done. They also have pride in what they're doing... that's very obvious. Although there's not so much I could learn from their presentation, at least their hard work gave me some glory for what I'm doing.

The most important presentation is about LED and LD on m-plane GaN which is scheduled for tomorrow at 9AM. I'll be there, for sure.

Met Prof. E* as soon as I returned to the laboratory this evening. There's a lot of thing on schedule to be done... but not to say anything here. Also got sample from Suzuki-san. And had some discussion with Nomura-san about the sample I asked him to grow on tomorrow. Now, actually, I'm doing XRD (x-ray-diffraction) scan for the sample I received from Suzuki-san just now. The characterization will finish tomorrow morning at 7:30AM (it takes 12 hour)... so tonight will be another sleepless night for me. I've to finish it before 8AM as it takes around 1 hour to go to Chubu Univ. from my university, by train and feeder-bus, to listen for the m-plane GaN LED/LD tomorrow morning at 9AM.

Okay, good luck for everybody! :)

Got my Onda VX-777!

Haha... the gadget I waited for a week finally arrived. So happy :)

Toki Premium Outlet Store

Yesterday, I went to Toki Premium outlet store in Toki-city, Gifu Prefecture with my room-mate (Kucai). I first thought that it was impossible to make it yesterday since the weather was raining hardly. But, we really made it! Haha! Kucai drove his car along the entire journey which took 2 hours for each single trip. Stopped at Sushiro (an Osakan sushi restaurant) at Tajimi-city (in Gifu Prefecture) on our way back to Nagoya. Happppy! :)
