Research Abstract

The device properties of AlN/diamond heterojunction p-channel FET were improved and the operation mechanism of this FET was investigated. AlN was grown on diamond substrates using metalorganic vapor phase epitaxy. Owing to the etching of AlN just below the source-drain electrodes by Cl2 gas and the adopting the Pd for ohmic contacts, the FET performance was drastically improved. The thermal treatment (1250 oC) in the mixed H2 and NH3 atmosphere for oxygen-terminated diamond surface produced the AlN with good adhesion to diamond substrates and the surface hole-carrier at the same time. Judged from the fact that the FET had a normally-on mode, AlN was considered to be worked as the protection and insulating layer.
