ABSTRACT:
An electron-emissive semiconductor device such as a photocathode or an electron multiplier, consists of separate regions of semiconductor material spaced apart by a barrier which reduces current flow between the regions. The barriers improve the performance of the device by preventing excess electron emission currents and reduce image spreading.
