Abstract : The separation between surface adsorption and reaction of GeH4 on a Si substrate was investigated by heating the surface with a Xe flash lamp in an ultraclean low-pressure environment. The GeH4 partial pressure dependence of the deposited Ge thickness and relationship between atomic layer thickness and the shot to shot time interval have been investigated. Single atomic layer deposition per flash lamp light shot has been realized for some process conditions. From electron diffraction patterns, a single-crystallinity was found for most substrate orientations.
