THIN FILM ACTIVE DEVICES
Abstract
The problem of collecting hot electrons from a metal by means of a simple metal-insulator interface is discussed. Backscattering out of the insulator is shown to be a serious problem if high collection efficiencies are desired. Fabrication of tunnel emitters for the Metal Edge Amplifier (MEA) was seriously hindered by shorting through the natural oxide of aluminum. A more fundamental examination of the oxidation process was begun and, in the meantime, attempts will be made to use evaporated insulators for device fabrication.
