We report an ab initio investigation of fast electron energy-loss probability in silicon and germanium nanowires. Computed energy loss spectra are characterized by a strong enhancement of the direct interband transition peak at low energy, in good agreement with experimental data. Our calculations predict an important diameter dependence of the bulk volume plasmon peak for very thin wires which is consistent with the blue shift observed experimentally in thicker wires.

Abstract

We report an ab initio investigation of fast electron energy-loss probability in silicon and germanium nanowires. Computed energy loss spectra are characterized by a strong enhancement of the direct interband transition peak at low energy, in good agreement with experimental data. Our calculations predict an important diameter dependence of the bulk volume plasmon peak for very thin wires which is consistent with the blue shift observed experimentally in thicker wires.
