The adsorption of sulfur on the tungsten (110) surface

The adsorption and desorption of S on a W(110) surface is studied by Auger electron spectroscopy (AES), low energy electron diffraction (LEED), work function change (δφ) measurements and thermal desorption spectroscopy (TDS). The evolution of the structure with coverage θ is quite different from that reported for S on Mo(110) and — at low coverages — from that of Te on W(110). At low coverages the structure indicates complex lateral interactions. The bonding changes with coverage similar to S on W(100). Evidence for more complex desorption kinetics than assumed in the past is presented.
