Surface-Potential-Based Compact Modeling of p-GaN Gate HEMTs [PDF]
Micromachines, 2021 We propose a surface potential (SP)-based compact model of p-GaN gate high electron mobility transistors (HEMTs) which solves the Poisson equation. The model includes all possible charges in the GaN channel layer, including the unintended Mg doping ...

Potential energy surfaces for gas-surface reactions [PDF]
Physical Chemistry Chemical Physics, 2011 A method for constructing the potential energy surface for reactions of a molecule with the surface of cleaved non-conducting crystals is reported. The method uses systematic fragmentation to express the total potential in terms of potential energy surfaces which describe reactions of relatively small molecules in the gas phase.

Surface tensions and surface potentials of acid solutions [PDF]
The Journal of Chemical Physics, 2010 A theory is presented which allows us to quantitatively calculate the excess surface tension of acid solutions. The H+, in the form of hydronium ion, is found to be strongly adsorbed to the solution-air interface. To account for the electrostatic potential difference measured experimentally, it is necessary to assume that the hydronium ion is oriented ...

Mapping the Electronic Surface Potential of Nanostructured Surfaces [PDF]
Physical Review Letters, 2009 We present a method for the quantitative determination of the surface potential landscape of nanostructured surfaces based on the local analysis of the lowest field emission resonances by scanning tunneling spectroscopy. The method has a lateral resolution of approximately 1 nm and is applied to elucidate the site-specific adsorption properties of the ...
