Charge-Population Based Dispersion Interactions for Molecules and Materials

Martin Stöhr, Georg S. Michelitsch, John C. Tully, Karsten Reuter, Reinhard J. Maurer, J. Chem. Phys., 144, 151101, (2016)

 A simple correlation between atomic polarizability and hybridization enables us to couple semi-empirical electronic structure methods with electron density-derived dispersion correction methods.

Interfacial charge rearrangement and intermolecular interactions: Density-functional theory study of free-base porphine adsorbed on Ag(111) and Cu(111)



Porphine on Ag(111)

Interfacial charge rearrangement and intermolecular interactions: Density-functional theory study of free-base porphine adsorbed on Ag(111) and Cu(111)

M. Müller, K. Diller, R. J. Maurer, K. Reuter, J. Chem. Phys., 144, 024701 (2016)

We study the interactions and the self-assembly behaviour of Porphine on Ag(111) and Cu(111). We find significant substrate-mediated, and negligible direct lateral interactions.
