Abstract
Abstract A solid-state atomic particle and X-ray detector comprising an N-type semiconductor crystal of high atomic number, coated with a metallic film of low atomic number. By making the metal-tosemiconductor interface abrupt, a Schottky barrier-type junction is produced. Atomic particles or X-rays can easily penetrate the metallic film but are absorbed in the semiconductor near the interface, producing electron-hole pairs in the depletion region. Holes which diffuse beyond the depletion region give rise to a current indicative of detection of X-rays or atomic particles.
