Photo-compton currents at material interfaces: Theory and experiment

Analytical formulae are presented for the electron number current, energy current and energy deposition at the photon irradiated interface between different materials. Representative results are shown and compared with previous experimental data. Experimental results are given for the electron number current as a function of interface materials, photon spectrum and photon angle of incidence. The experimental results are compared to the predictions of the analytical formulae and the Monte Carlo code SANDYL.
