China's first back-gate ZnO nanorod field-effect transistor
China's first back-gate ZnO nanorod field-effect transistor

Abstract:
Recently, zinc oxide (ZnO) nanorod field-effect transistor (FET), the first of its kind as a nano device in China, was successfully fabricated by scientists with the CAS Institute of Microelectronics, Chinese Academy of Sciences (IME).

China's first ZnO nanorod field-effect transistor fabricated in IMECAS

China | Posted on October 22nd, 2008

ZnO is a wide bandgap semiconductor and an important multifunctional material. The ZnO nano materials, such as nanowires, nanorods, nanobands and nanorings, attract intense worldwide attention for their unique optical, semiconducting and piezoelectric properties. At present, Chinese scientists in this filed mainly focus their research on material growth and diode development.

A research group headed by Prof. ZHANG Haiying from IME came up with a unique "bottom-up" method for designing and developing nano devices. Through the regular contact photolithography technology, they employed ZnO nanorods as the channel material and fabricated a metal-oxide-semiconductor FET by combining gate oxide and back gate metal, which displayed satisfying results.

Next, Prof. Zhang and her colleagues will further advance the technology in order to develop nanowires with an even smaller diameter and improve the performance of the devices, raising solutions to key problems in practical use.
