Abstract

The study of photoemissive devices has been going on for over about 40 years with the result that photocathodes are now the energy-conversion elements in many photon-detector and image-intensifier tubes. Technical interest has generally been concerned with photon detection in the visible and infrared regions of the electromagnetic spectrum. This interest resulted in an early recognition of the importance of the alkali metals, in particular, cesium, the element with the lowest work function. The understanding of the physics of semiconductors that has been gained in this time period has without doubt contributed to the further development of photocathodes, but it is still true to comment that the more efficient cathodes are the products of lengthy and largely empirical procedures.
