Abstract

Potential fluctuations and hot electron effects associated with the Coulomb interaction among electrons are investigated with the self-consistent 3D MC simulations under the thermal equilibrium condition. It is demonstrated that the present simulations could successfully simulate the collective plasma waves owing to careful optimizations of simulation parameters. As a result, the potential fluctuations due to the plasma waves greatly disturb the local density of states and induce the band-tailing effects, which lead to the electron kinetic energy much larger than that of room temperature, whose magnitude coincides well with the previous results obtained from the 2D MC simulations.
