Abstract
An enhancement mode diamond FET using a hydrogen-terminated surface as hole conductive channel has been fabricated with 200 V gate to drain breakdown voltage. At the 8.5-μm gate length the maximum drain current was 22 mA/mm. 90 mA/mm maximum drain current was obtained at a gate length of 3.0 μm. Scaling to below 1 μm gate length assuming undegraded breakdown conditions will result in a projected RF power handling capability above 6 W/mm.
