High gain 4H-SiC static induction transistors using novel sub-micron airbridging

For the first time, high gain 4H-SiC static induction transistors (SITs) have been fabricated using a sub-micron source airbridging technique. These devices exhibit record 15 dB small signal gain at 3 GHz. This represents the highest gain yet reported for a SIT structure in any semiconductor.
