The analysis of a 6H silicon carbide (SiC) photoconductive switch, designed and packaged for high-power, linear-mode operations, is presented. The switch, fabricated from semi-insulating compensated SiC, is triggered by an optical source with photon energy less than the band-gap energy. Simulation models incorporating the effects of vanadium trap and nitrogen dopant in the compensation material show I-V characteristics that agree with measured values. The photoconductive switch has improved rise-time characteristics as compared to a gallium arsenide (GaAs) switch. The analysis also shows that improved performance at high power is possible through passivation using high-permittivity dielectric near the contact-semiconductor interface and by placing a p(+) layer next to the cathode.
