  • Gallium arsenide photocathodes
    Patent number: 4115223
    Abstract: This invention comprises methods and apparatus for bonding a transmission type III-V photocathode to a transparent substrate. An R.F. susceptor arrangement produces a marked temperature gradient for allowing the surface of the glass to conform to the shape of the semiconductor material without softening the bulk of the glass. The bonded assembly is then carefully annealed in an annealing furnace.
