Submicron gate-length metal semiconductor field effect transistors (mesfets) were fabricated on hydrogen-terminated - large grain polycrystalline diamond. Devices showed high drain-source current (140 ma/mm) and large transconductance values (50 ms/mm), with a cut off frequency f(t)=10 ghz and a maximum oscillation frequency, f(max), up to 35 ghz. These values suggest device microwave operation in the k-band.

Abstract
Submicron gate-length metal semiconductor field effect transistors (mesfets) were fabricated on hydrogen-terminated - large grain polycrystalline diamond. Devices showed high drain-source current (140 ma/mm) and large transconductance values (50 ms/mm), with a cut off frequency f(t)=10 ghz and a maximum oscillation frequency, f(max), up to 35 ghz. These values suggest device microwave operation in the k-band.File in questo prodotto:
