Ab-initio calculation of the real contact area on the atomic scale
Michael Wolloch, Gregor Feldbauer, Peter Mohn +2
We present a novel approach to determine the onset of contact between a tip and a surface. The real contact area depending on the distance is calculated using Bader's quantum theor…

Adhesion and material transfer between contacting Al and TiN surfaces from first principles
Gregor Feldbauer, Michael Wolloch, Pedro O. Bedolla +3
A series of density functional theory (DFT) simulations was performed to investigate the approach, contact, and subsequent separation of two atomically flat surfaces consisting of…

Effects of van der Waals Interactions in the Adsorption of Isooctane and Ethanol on Fe(100) Surfaces
Pedro O. Bedolla, Gregor Feldbauer, Michael Wolloch +5
Van der Waals (vdW) forces play a fundamental role in the structure and behavior of diverse systems. Thanks to development of functionals that include non-local correlation, it is…
