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.
Abstract translation: 诸如光电阴极或电子倍增器的电子发射半导体器件由分隔开的屏障分隔的半导体材料区域组成,这些区域减少了区域之间的电流。 屏障通过防止过量的电子发射电流并减少图像扩散来提高器件的性能。
