Abstract: This invention involves a solid state charge carrier beam deflection apparatus (solid-state equivalent of a cathode-ray tube), utilizing a high resistivity semiconductor body for the propagation medium of the beam. A relatively high electric field in the semiconductory body is utilized to propel a beam of electrons or holes in a direction from a rear surface to a front surface of the body, the beam being characterized by a confined cross section throughout the beam''s trajectory. Deflection of the beam in the body can be accomplished by transverse electric or magnetic field; detection of the beam can be accomplished by a variety of means, including ohmic contacts and Schottky barrier diodes located at the front surface of the semiconductor body.
