Significance of local density of states in the scanning tunneling microscopy imaging of alkanethiol self-assembled monolayers

Article Abstract:

The scanning tunneling microscopy (STM) study of alkanethiol self-assembled monolayers (SAMs) is presented as a function of the bias voltage, tunneling current, and tip-termini separation. The results have shown that the corresponding local density of states (LDOS) might override the physical height variations in the STM topographic contrast for alkanethiol SAM systems.

Identification of alcohol dehydration sites on an oxide surface by scanning tunneling microscopy

Article Abstract:

High-speed scanning tunneling microscopy (STM), temperature-programmed desorption (TPD), Auger electron spectroscopy and low-energy electron diffraction (LEED) were applied to study the (001) surface of monoclinic gama-WO3, and to determine the structure and reactivity of active sites on this surface. The respective results were detailed.
