Abstract :
The room temperature adsorption of H2S on InP(110) may be understood as a cooperative dissociation in which H+ and SH− bond to the surface anion and cation, respectively. Synchrotron radiation angle resolved ultraviolet photoelectron spectroscopy (ARUPS) and near edge X-ray absorption fine structure (NEXAFS) are used to probe the filled and vacant orbital levels of the adsorbate complex. The NEXAFS results are consistent with the location of the sulphur in the continued layer anion site in agreement with recent X-ray standing wave measurements.
