Shao Chunlin: suggestions on the development of LED in China

Under the tutelage of the famous scholar Meno Jungyi, the father of Akasaki Yong witnessed the nitride, the optoelectronic industry development in Japan and the world's leading 20 years, Shao Chunlin has become a world-class field of Optoelectronics Research circle. But for over sixty years, Shao Chunlin, home is perhaps the true cause of start. Shao Chunlin began his master's and doctoral degrees in Japan from 1980, in addition to returning the short 4 years, Shao Chunlin has been working for more than 20 years of life in Japan, their children also in Japan, but Shao Chunlin and his wife air plant, still maintained a China nationality. Shao Chunlin has been unable to remember how many times he returned to China, and received a number of domestic visits to japan. Shao Chunlin said, in fact, the exchange with the domestic industry has never stopped.

Shao Chunlin had two options, one is to stay in Nagoya Industrial University Japan nano devices and systems research center as a professor doing research with Dr., this research center has a world-class optoelectronic semiconductor research equipment, research scope from the growth of epitaxial wafers and devices to high power package, is very extensive, every year there are 150 million yen the research funding to stay well to retire at the age of 70. Another option is to return home and lead a Chinese team back home.

For Shao Chunlin, home is not a deliberate choice, there is no domestic research institutions can and nano devices and systems research center, Nagoya University of technology at present, enterprise scale is still small, many companies are still in the initial stage. But Shao Chunlin believes that he can not give up the opportunity to enhance the domestic optoelectronic semiconductor industry, with this opportunity, perhaps the most important cause of the life of Shao Chunlin.

Father of nitride

Shao Chunlin recalled, in 1980, graduate student at Nagoya University, when the instructor is Professor Meno Jungyi, and his doctoral tutor is Professor Akasaki Yong. Under the guidance of Professor Sakai Shiro, Shao Chunlin and another important figure in the field of optoelectronics, Japan, with an office in, mainly engaged in the development of MOCVD devices and optoelectronic devices. Later became the famous MOCVD Dayang acid equipment supply company of No. 1 and No. 2 prototype are involved in the development of Shao Chunlin. At present, the company provides a free MOCVD equipment to the center, each year also provides a lot of research funding, the main purpose is to help the center to verify the performance of the equipment.

Currently in Japan, but also the world's most outstanding LED enterprise is Nichia, TOYOTA synthesis, which is acid MOCVD accounted for 80% of the market in Japan, which is Japan's leading LED an important guarantee of the world. Which Professor Akasaki Yong is the synthesis of TOYOTA technical guidance, technology is the source of Dayang acid Nagoya Institute of nano devices and systems research center Shao Chunlin's. The most famous Nichia in 1987 is still very small, less than 200 people, and later accepted the recommendation of Sakai Shiro, began to engage in the nitride semiconductor. Sakai Shiro later asked to study in the United States, Nichia appointed an assistant, the assistant is later known as the father of the Nakamura Shuji blue. Recommended by Professor Sakai Shiro, or graduate student Nakamura Shuji went to Florida University to study MOCVD technology. So, at that time no MOCVD technology Nichia chooses a subject with MOCVD growth method of nitride semiconductor. It is Nakamura Shuji's research, the Nichia growing from a small company for the world famous LED leading enterprises, the output value from 2 billion yen to 20 billion yen rose.

Nakamura Shuji left Nichia, to continue to do research at the Stanford University, at the same time every Monday day frequency to the American CREE company to do the technical guidance. Later CREE became the company to compete with Nichia chemical phase.

Shao Chunlin introduction, before the 90s of last century, researchers for a long time to find the material can be produced blue LED. In the nitride before success, almost all experts in this area are about ZnSe based II-VI compound semiconductor, only the Japanese Nagoya University professor Akasaki Yong first began to study the nitride semiconductor. Until now he was the most active leader in the field. His team has made many breakthroughs in basic research on nitride. So most experts in the field think he is the father of nitrides.

In 1980, nano devices and systems research center, Nagoya University of technology has not been established, study room named by Professor Meno Jungyi is mainly engaged in semiconductor gallium arsenic compounds, is the main direction of light emitting devices, sensors and solar cells. In 1994, ten years of the Japanese Ministry of education to develop plans for optoelectronic devices, and there was led by Professor Meno Jungyi, research center for nano devices and systems now, Professor Meno Jungyi served as the first director. The research center is mainly engaged in the study of gallium nitride (GaN) materials. Last year, the end of the ten year plan, after expert review, the research center continues to study.

At present, the center has a MOCVD of four sets of equipment, belonging to the key research center at the Nihon University, LED material and device can be made from red to UV spectra, in the three main directions of LED technology -- high quality epitaxial wafer, high-efficiency fluorescent powder and high power package, epitaxial films and packaging research power in the world advanced level.

Shao Chunlin himself and the Japanese LED field representative communication "on", says while the circle outside to generalize this relationship. In fact, it is a long time with the Japanese scholars
