Tip-dependent contrast in STM imaging of adsorbed sulfur layers: theory and experiment
Sulfur atoms adsorbed on the Re(0001) surface from several different ordered structures as a function of sulfur coverage. Sudden changes in the detailed appearance of atomic-resolution STM images of these structures have been observed. Theoretical image simulations using electron scattering quantum...

| description | Sulfur atoms adsorbed on the Re(0001) surface from several different ordered structures as a function of sulfur coverage. Sudden changes in the detailed appearance of atomic-resolution STM images of these structures have been observed. Theoretical image simulations using electron scattering quantum chemical (ESQC) methods show that the image structure is strongly dependent on the chemical identity of the STM tip atom. Observed changes in the sulfur images can be caused by changes from rhenium-terminated to sulfur-terminated STM tips. These results demonstrate the value of ESQC calculations for STM image interpretation. |
