A theory is presented for vacuum tunneling between a real solid surface and a model probe with a locally spherical tip, applicable to the recently developed "scanning tunneling microscope." Calculations for 2\ifmmode\times\else\texttimes\fi{}1 and 3\ifmmode\times\else\texttimes\fi{}1 reconstructions of Au(110) are in excellent agreement with recent experimental results, if an effective radius of curvature of 9 \AA{} is assumed for the tip.read more

TL;DR: A localized interfacial charge rearrangement between the water hexamer and P atoms underneath that is responsible for the reversible desorption and adsorption of water molecules by changing the sample bias polarity from positive to negative is found, offering a promising strategy for engineering the electronic properties of blueP.

TL;DR: In this article, a theoretical approach based on the scattering of electrons by rough surfaces is presented to explaintunnel-vacuum experiments, where the electrodes, the tip as well as the crystal surface are described by a jellium model.

Influence of the support on stabilizing local defects in strained monolayer oxide films.
TL;DR: This paper uses scanning tunneling microscopy (STM) and density functional theory (DFT) modeling to investigate the structure and energetics of S-W and divacancy defects in a honeycomb Ti2O3 monolayer grown on an Au(111) substrate, and finds that at the divacancies defect sites there is a local reduction of the charge transfer between the film and the substrate.
