HOT ELECTRON EFFECTS IN SILVER HALIDES IN QUANTUM LIMIT.

Abstract

Hot electron effects in quantum limit were investigated by observing photoconductivity in pure AgCl and AgBr crystals at 4. 2K up to 13kV/cm and 52koe using a fast-pulse technique with blocking electrodes. The results are discussed in terms of the electron excitation from the N equals O Landau level to the N equals 1 level abruptly enhanced above a critical field that is related to the magnetic field through the cyclotron radius and frequency.
