STM/STS Study of the Sb (111) Surface - ScienceDirect
2015年1月1日 · However, using scanning tunneling microscopy (STM) and spectroscopy (STS) we demonstrated that apart from islands equal in thickness to the double layer, steps of one atomic layer in height also exist on the cleaved Sb (111) surface. Formation of “unpaired” (111) planes on the surface leads to a local break of conditions of Peierls transition.

STM studies of the initial stages of growth of Sb on Si(100) surfaces
1999年3月1日 · In this paper, we report STM and STS studies of the initial stages of growth of Sb on Si (001) over a wide range of substrate temperature (room temperature to 500°C). At low temperatures, the Sb resides on top of the Si (001) surface as clusters (Sb 4) or dimers.

Peculiar Structural Phase of a Single-Atom-Thick Layer of Antimony
Atomically resolved scanning tunneling microscopy (STM) measurements together with the results of density functional theory (DFT) calculations show the perfect flatness of the layer without atom buckling. The arrangement of the Sb atoms in the layer reproduces the periodicity of the tungsten substrate along the [001] direction.
