Field- and photon-enhanced field emission from thin-film field-emission devices
Electronics Letters, 1968 Thin-film sandwich devices of CdS-SiO-metal have been made. They have current/voltage behaviour characteristics of field emission from semiconductors. With reverse bias, the current is very much smaller. The field-emission current is greatly enhanced by illuminating the device with 2.41 and 2.54eV photons (from an argon-ion laser).
