Research Abstract

We developed high-performance ZnO-based FETs operated in gigahertz frequency range. First, a hetero-MIS transistor was employed to exhibit high-frequency performance. A very high cutoff frequency of as high as 1.7 GHz was obtained. Sputter-deposited ZnO thin-film transistors were proved to exhibit comparable high-frequency performance by measuring their static performance.
