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. It is recognized that the hot electron effect in strong magnetic fields occurs above the critical field EH related to the magnetic field H through the equation eEHrc =ħωc, where rc and ωe are the cyclotron radius and frequency for electrons. These results are discussed in terms of the electron excitation from the N=0 Landau level to the N=1 level abruptly enhanced above EH.
