Self-Limiting Adsorption of SiCl2H2 and Its Application to the Layer-by-Layer Photochemical Process

Abstract
Adsorption of SiCl2H2 on the Ge(100) clean surface is investigated by X-ray photoelectron spectroscopy and thermal desorption spectrum measurement. It is concluded that the adsorption is self-limiting at temperatures below 350°C, and that the surface is reactivated by synchrotron radiation. The sequential processes of self-limiting adsorption of SiCl2H2 and synchrotron radiation are promising for development of Si atomic layer epitaxy.
