CRITERIA FOR RADIATION INSENSITIVE INSULATORS.
Abstract
A review of the accepted theory of radiation induced conductivity in insulators is presented. The recovery from a radiation pulse is analyzed in some detail and it is shown that in high resistivity materials the recovery time is limited by the normal conductivity of the insulator. Radiation insensitive insulators for use with solid state circuits should have resistivity in the range 1,000,000 - 10,000,000 ohms - cm, short carrier lifetime, and a minimum of trapping. In addition, ohmic contacts to the insulator to allow return of electrons driven off by the radiation must be made relatively easily. Semi-insulating gallium arsenide is suggested as a material fulfilling these criteria. (Author)
