Beam-Bombarded Diodes.
Abstract
The Electron-Beam-Ionized Semiconductor Device (EBIRD) has shown evidence of being useful in a number of electronic devices. It was decided to investigate a configuration using a grid-modulated input system and the semiconductor diode mounted in a 50-ohm impedance cable as the output section. A demountable test vehicle was designed and built using commercial electron tube grid-cathode mounts for the input portion of the tube. Data were collected on two diodes at frequencies up to 5 MHz, which indicates that high transconductance at low beam currents will be realizable. Tests on one of the diodes at 250 MHz resulted in a gain of less than one. (Author)
