Nagoya University professor Yashiro Akino uses the research results that have won him the Nobel Prize. The blue light-emitting diodes have successfully developed semiconductor materials with excellent energy-saving effect. At present, they have found ways to apply this material to household appliances such as air conditioners. Prof. Amano It also cooperated with private companies such as Toyota Motor Industry Corporation and Denso Co., Ltd. and strived to reduce costs and put it into practical use within two years.
According to the report, in 2014, Professor Amano and Dr. Akazaki of Meijo University, and Dr. Shuji Nakamura of the University of California, USA, won the Nobel Prize in physics. The results of Amano’s research, the blue LED made of GaN is also widely available. Acclaimed. He also used gallium nitride as raw material this time to develop a 'power semiconductor' that can manipulate power.
According to the report, the researchers created a small piece of semiconductor about 1 mm square, which can stably transmit the 10 amps of current needed during the use of household appliances. If it is used in servers that store large amounts of data or in electrical appliances such as air conditioners, it will be able to Save nearly 10% of power consumption.
It is reported that gallium nitride is prone to defects during the processing of semiconductors, which generates heat and causes deterioration of the materials. Prof. Ario and other researchers have improved the durability of the materials. Even if defects occur, it is difficult to cause material deterioration. After the durability problem, the new materials have reached the commercial level. By cooperating with private companies, it is expected that the cost will be reduced to one percent after two years.
Reportedly, it is reported that once the manufacturing cost is reduced to less than 1 percent, this new product is expected to replace the existing power semiconductors made of silicon and silicon carbide.
According to the report, power semiconductor materials can be used not only in home appliances but also in the field of highly competitive research and development of electric vehicles. Professor Arano's goal is to further promote the development of new materials for electric cars in the future.
According to the report, the research project was initiated by the Ministry of Education, Culture, Sports, Science, and Science, with Professor Akino as the core, together with about 40 companies such as Toyota Motor Corporation. The companies and universities brought their own experimental data, and they overcame the existence of practical applications. Problem: The current that has hindered the use of GaN semiconductor devices in household appliances has also found a solution. The technical problems have been completely eliminated.
