Radiation Induced Electrical Current and Voltage in Dielectric Structures.

摘要

A computational technique has been developed in one dimension for prediction of radiation-induced electrical currents and electrostatic fields in metal-dielectric slab structures. High energy radiation transport effects produce divergent electron currents,time-dependent electrostatic fields,and time-dependent conduction electron currents. These effects are considered and the computational technique predicts electric fields approaching breakdown intensity and time-dependent electrode currents which may even change sign. Brief comments on application of the technique to field effect electronic devices are included. Results are given for several metal-dielectric slab combinations under 200keV and 1.25MeV photon irradiations.
