Trip to Shodojima Island (Kagawa Prefecture)

Just reached home from 2-day trip to Shodojima Island, just next to Kagawa in Shikoku Island, south of Himeji / Kobe city. Himeji is located 5 hours from Nagoya through expressway. We need to take a 90 minutes ferry ride to reach the island. The scenery during the ferry ride is just amazing!

I'm having very bad cold, and very tired too. Hope I could updatev this post with some pictures very soon. Just took some paracetamol and actifed tablets... my mind is so dizzy now. See you then ^_^

Miss you Hui :-)

Iraqi Journalist Threw Shoes at Bush at News Conference

Wow! This is amazing! I wonder what would happen if the shoes hit Mr. President's face.

"Jalan-Jalan" around Nagoya


Going around Nagoya yesterday with Prof. Gadkari. It was quite interesting, because he demanded to go back from Osu-Kannon to his hotel at Nagoya Station area by BUS. Frankly speaking, I never tried a bus in the city because train/subway is more efficient and has better reach in the city. That brought my first experience boarding a bus in Nagoya city, haha ^_^ We board a Meitetsu bus, not the normal blue/white-colored Nagoya city bus because the Meitetsu has better frequency (from the chart at the bus booth). Both have the same price plan. A Japanese guy helped us regarding the method.

We need to board the bus by back door, take a coupun (ticket??) at the door and get seated. When getting off, I need to change my JPY1,000 yen note to get JPY100 yen coin first (machine is at the driver seat). After that, put the coupon took at door during boarding into payment machine first, followed by JPY200 yen coin. [These are notes for myself actually].
Before that, I brought him to an Indian/Pakistani buffet restaurant at Kanayama. He was extremely happy being able to taste Indian cuisine, after a week of Japanese foods. Also met Brother Azlan and his family, and also Azmi, Rizal, and new postgraduate student from UTeM, at the same buffet restaurant.

IUMRS-ICA

http://www.iumrs-ica2008.jp/index.html



Went to International Union of Materials Research Society - International Conference in Asia (IUMRS-ICA) at Nagoya Congress Center, yesterday. Went there to meet Prof. Gadkari, actually. I had discussion with a Chinese researcher presenting about Gallium Nitride (GaN) bulk crystal growth from Gifu University (Japan). The topic was near to what I'm doing for my research, so it's quite a wonderful discussion. Also had discussion about TiO2 deposition with other researcher, also in my interest to be applied in mirror facet coating for my laser-diode (LD).

Gadkari also taught me new thing, it's about thermo-photovoltaic. This is really amazing! Normal solar-cell use photovoltaic mechanism to absorb photon (light) energy from sun, however, in thermo-photovoltaic, even small thermal energy from human body can be used to generate another energy! So, you can generate energy from not only sunlight, but also from sun-heat during the day. In the night, when there is no sunlight, heat from sleeping human body itself can generate energy! WOW! Gadkari is thinking to use his I*S* to enable this, due to its small band-gap, just around 0.2 eV. With small band-gap, even a small source energy can generate another energy. Haha... never been taught this thing at my laboratory. I realized today that my research group here're toooo stereotype!

Okay, that's all for this morning. Will go for "jalan-jalan" (shopping, eating out) with Gadkari this afternoon.

Pictures of Muslim Pilgrims in Mekkah (Mecca) during Hajj

Insya'Allah, I will also be here at least once in the future :)


Pilgrims pray at the birthplace of prophet Mohammed at the Grand Mosque, Islam's holiest shrine where some 2 million Muslims have been gathering for weeks in advance of the annual Hajj pilgrimage in Mecca, Saudi Arabia on December 4, 2008. More than two million Muslims head to the holy city of Mecca, Saudi Arabia to make the annual Hajj pilgrimage. All fit and financially able Muslims are expected to perform the Hajj at least once in their life. (UPI Photo/Mohammad Kheirkhah)

Happy Aidiladha and Welcome :)

Tonight is a Muslim's special night because we will have Aidiladha celebration tomorrow. At 7PM last night, Malaysian students living in this city gathered and had "takbir", Islam-related talk, and dinner held at Nagoya Institute of Technology.

However, I only went for the "takbir" ceremony, as I have to take Prof. Gadkari coming from Mumbai University at Nagoya Chubu International Airport. He will attend IUMRS-ICA meeting at Nagoya Congress Center starting from Dec 9th till 12th. I departed from my university at 8PM, and arrived at the airport around 40 min later. Dr Gadkari came out of the immigration check at around 9:20PM... waahhh! Both of us were surprised to be able to meet again after almost half-a-year.

Actually, I came to know Dr. Gadkari when we were both attending MRS meeting in Chongqing, China. His work is in compound semiconductor, ... he's making the substrate to be exact. Mine is in the semiconductor growth and device... so, each of us have good interest in each other's work. He gave me a lot of advice in what I should pursuit in my research and life, and I appreciate him so so much. It's hard to find such easily approachable professor around me in Nagoya.

It's already too late now. I have to wake up early tomorrow morning as I will join my juniors to go to a special praying for Aidiladha next morning. I have to be at laboratory before and after that. In the evening, I will spend some time with Dr. Gadkari to show him some good restaurants around his hotel at Nagoya station area.

That's all for now.

You're always in my heart :) Wo ye xiang ni, Hui Hui ^^

18 Hours of Photo-Luminescence (PL) Mapping

Seems like I miscalculated the time for PL mapping of my LD sample. Did many times PL mapping for blue-violet LED samples before, normally it takes around 4 hours to map a 2 inch wafer.

This time, it is a LD sample. When I tested it this morning, the light intensity from the surface is very low, probably due to the LD structure itself which holds light within the active layer region (prevents light from being leaked to the surface). Therefore, I need to increase the detector scanning time to 3 sec (normally 0.2 sec) for each scan. There're 97 times scan of the circle 2" wafer surface with 0.5 mm pitch between each other. The stage controller also needs a few seconds to move the He-Cd laser to each pitch position, and the workstation also becomes slower and slower with increasing scan times... altogether causing an extremely slow experiments!

Normally, I could finish 2 samples in a day for normal LED samples, but for this LD sample, it takes my 2 days working hours just to finish a single sample. It's already 1:15AM in the midnight, I wonder where I would sleep tonight...
