Transversely-illuminated high current photoconductive switches with geometry-constrained conductivity path
Patent
·
OSTI ID:1252200
A photoconductive switch having a wide bandgap semiconductor material substrate between opposing electrodes, with one of the electrodes having an aperture or apertures at an electrode-substrate interface for transversely directing radiation therethrough from a radiation source into a triple junction region of the substrate, so as to geometrically constrain the conductivity path to within the triple junction region.
