Monte Carlo study of spatio-temporal distributions of photo-dember field and THz radiation from InAs

Abstract:

The spatio-temporal distributions of photo-Dember fields on the semiconductor surface of InAs and the pump wavelength-dependent dynamics of THz radiation from this semiconductor have been investigated with the method of ensemble Monte Carlo Simulation. Our simulations not only confirm the experimental results [P. Gu et al., J. Appl. Phys. 91, 5533(2002)] that the pump wavelength-dependent feature of THz pulse amplitudes for InAs is completely different with that for GaAs, but also point out that the corresponding mechanism is the characteristics of photo-Dember fields. © Springer Science+Business Media, LLC 2006.
