High current photosensitive electronic switch

摘要

The switch described uses interdigitated indium and silver electrodes closely spaced on the surface of a photosensitive semiconductor and an intense source of light such as a xenon flashlamp. The semiconductor and electrodes may be arranged on the surface inner of a hollow spherical cavity at the centre of which is the light source. The switch is designed to carry high currents (typically 10A) at relatively low voltages (typically 5kV).
