Abstract:The reaction between a silicon monolayer deposited on Pt(111) by chemical vapor deposition (CVD) using silane (SiH$\sb4)$ is described. Using Auger electron spectroscopy (AES), Si was found to readily diffuse into the Pt substrate and sequentially form at least two unique intermetallic Pt-Si surface structural phases with $(\surd7$ x $\surd7)R\pm19.1\sp\circ$ and $(\surd19$ x $\surd19)R\pm23.4\sp\circ$ real space unit cells as characterized by low energy electron diffraction (LEED). The reactive properties of each overlayer were studied, with respect to the clean Pt(111) surface, using CO as a chemisorption probe.
