Abstract

We investigate the effects of Nd:YAG and excimer laser irradiation on the Ge(100) surface under UHV conditions over a temperature range 140 < T(K) < 300 using the surface sensitive probe of He atom diffraction. We study the effects of irradiation on surface damage and order using the apparent (2×1) ࢐ c(2×4) transition. We monitor surface contamination in situ. The temporal thermal response is modeled theoretically to aid in assessing the experimental results. The capability to maintain a Ge(100) surface at low temperatures free of contamination and well ordered is demonstrated.

[11] Simple Debye-Waller formulae generally do not fit He diffraction results well, in part as the result of scattering resonances from bound states. These, however, are weak for both the Si(lOO) and Ge(100) surfaces due to the presence of disorder.Google Scholar
