Abstract
Abstract A semiconductive junction device comprises a thin layer of a glassy amorphous material exhibiting one type of conductivity (either N or P) disposed upon a semiconductive substrate possessing the other kind of conductivity. The glassy layer is sufficiently thin that it exhibits a useful level of conductivity. Preferably, the glassy layer is ion impermeable so that the device remains stable under a wide range of operating conditions. These junctions behave as diodes and can be incorporated in a wide variety of complex semiconductive devices.
