Structural and electronic properties of Pt modified Au(100) surface.

Investigations on electronic and geometric structures of platinum adsorbed on monocrystalline gold surfaces are important for understanding the remarkable catalytic properties of bimetallic Pt-Au systems. Herein, the morphology of quasi-hexagonal (hex) Au(100) surface after deposition of platinum for coverage up to 0.5 monolayer (ML) has been investigated by scanning tunneling microscopy (STM).

Influence of Graphite Layer on Electronic Properties of MgO/6H-SiC(0001) Interface.

This paper concerns research on magnesium oxide layers in terms of their potential use as a gate material for SiC MOSFET structures. The two basic systems of MgO/SiC(0001) and MgO/graphite/SiC(0001) were deeply investigated in situ under ultrahigh vacuum (UHV). In both cases, the MgO layers were obtained by a reactive evaporation method.

Coexistence of nanowire-like hex and (1 × 1) phases in the topmost layer of Au(100) surface.

Scanning tunneling microscopy and density functional theory calculations were used to study the structure of the Au(100) surface after ion bombardment. The results indicate a development of two phases: the quasi-hexagonal (hex) and the (1 × 1) on the surface. A decrease in the number of surface atoms caused by ion bombardment leads to the development of a coexistence of phases inside the surface layer.

Phthalocyanine arrangements on Ag(100): From pure overlayers of CoPc and FCuPc to bimolecular heterostructure.

We have utilized scanning tunneling microscopy (STM) and low energy electron diffraction to determine the structural properties of two types of metal-phthalocyanines (MPcs), i.e., cobalt-phthalocyanine (CoPc) and hexadecafluorinated copper-phthalocyanine (FCuPc) on the Ag(100) surface.
