Taipei, April 15 (CNA) A research led by a professor from National Chiao Tung University (NCTU) said Monday it has built a new type of high electron mobility transistor (HEMT) that has the highest oscillation frequency in the world.

The research paper on the latest HEMT technology, which could be applied in the fields of imaging system and biomedical testing, was published by the Japan Society of Applied Physics, the team said.

The new device could be reduced to as small as 40 nanometers, the researchers said, noting that 3C products are trending toward high speed and small size. HEMTs play an important role in speed performance, they explained.

With a high frequency of 710 GHz that could almost be converted into light, the new HEMT can decrease the total power consumption of 3C products and improve image resolution in remote atmospheric sensing and space exploration applications, the researchers said.

The team said it has signed on to various cooperative projects with Panasonic Corp. of Japan and aerospace companies in the United States and hopes to work with local firms to apply the technology to everyday products.

The research team was led by Edward-Yi Chang, a professor at NCTU's Department of Materials Science and Engineering, and included Hsu Heng-tung, associate professor at Yuan Ze University's Department of Communications Engineering, and Yasuyuki Miyamoto from Tokyo Institute of Technology in Japan.
