Diffraction and Electron Energy Loss to Plasmons in Silicon Slabs

Abstract

Dynamic diffraction patterns have been calculated for 25-nm thick slabs of silicon with [001], [111], and [110] faces for a 120 keV electron beam. The calculation used the mixed dynamical form factor in the dielectric formulation. Dielectric matrices with wave-vector and frequency dependence were calculated within the Local Density Approximation and Random Phase Approximation (LDA/RPA). The energy losses, 10 eV to 25 eV, were taken to span the plasmon peak. Near the zone axes, the results show the preservation of elastic contrast and both excess and deficit Kikuchi lines.
