A research team led by a professor from National Chiao Tung University yesterday said it had 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 systems and biomedical testing, was published by the Japan Society of Applied Physics, the team said.

The transistor could be reduced to as small as 40 nanometers, the researchers said, adding that 3C — computers, communications and consumer — products are trending toward high speed and small size.

HEMTs play an important role in speed performance, they said.

With a high frequency of 710GHz that could almost be converted into light, the new HEMT can reduce 3C products’ power consumption 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 US, and hopes to work with local firms to apply the technology to everyday products.

The research team was led by Edward Chang (張翼), a professor at the university’s Department of Materials Science and Engineering, and included Hsu Heng-tung (許恆通), an associate professor at Yuan Ze University’s Department of Communications Engineering, and Yasuyuki Miyamoto from the Tokyo Institute of Technology in Japan.
