AIRBED: a simpli?ed density functional theory model for physisorption on surfaces (2019)
Journal Article
Mason, S. E., Beton, P. H., & Besley, N. A. (2019). AIRBED: a simpli?ed density functional theory model for physisorption on surfaces. Journal of Chemical Theory and Computation, 15(10), 5628-5634. https://doi.org/10.1021/acs.jctc.9b00576

Dispersion interactions are commonly included in density functional theory (DFT) calculations through the addition of an empirical correction. In this study, a modi?cation is made to the damping function in DFT-D2 calculations, to describe repulsion...

The regular packing of atoms, molecules and nanoparticles provides the basis for the understanding of structural order within condensed phases of matter. Typically the constituent particles are considered to be rigid with a fixed shape. Here we show,... Read More about Ordering, Flexibility and Frustration in Arrays of Porphyrin Nanorings.

Direct band-gap crossover in epitaxial monolayer boron nitride (2019)
Journal Article
