Structure of Sulphur-Passivated InP(100)-(1×1) Surface
Published online by Cambridge University Press: 25 February 2011
Abstract
X-ray photoelectron spectroscopy, X-ray photoelectron diffraction, and S K edge X-ray absorption near-edge structure were used to characterize the air-stable S-passivated InP(100)-(lxl) surface prepared in (NH4)2S solution. The results show that one monolayer of sulphur which is bonded only to In is adsorbed on the surface. The S is found to occupy bridge-bonded sites, and the orientation of the In-S bond is determined to be in the [011] azimuth, with an In-S-In bridge-bond angle of about 100°.
