Theory of Polar Corrections to Donor Binding
G. D. Mahan, Kristian Berland
We calculate the optical phonon correction to the binding energy of electrons to donors in cubic materials. Previous theories calculated the Rydberg energy reduced by the effective…
Evaluation of New Density Functional with Account of van der Waals Forces by Use of Experimental H2 Physisorption Data on Cu(111)
Kyuho Lee, André K Kelkkanen, Kristian Berland +5
Detailed experimental data for physisorption potential-energy curves of H2 on low-indexed faces of Cu challenge theory. Recently, density-functional theory has been developed to al…
Response of the Shockley surface state to an external electrical field: A density-functional theory study of Cu(111)
K. Berland, T. L. Einstein, P. Hyldgaard
The response of the Cu(111) Shockley surface state to an external electrical field is characterized by combining a density-functional theory calculation for a slab geometry with an…
Graphene Nanogap for Gate Tunable Quantum Coherent Single Molecule Electronics
A. Bergvall, K. Berland, P. Hyldgaard +2
We present atomistic calculations of quantum coherent electron transport through fulleropyrrolidine terminated molecules bridging a graphene nanogap. We predict that three difficul…
Polarization-balanced design of AlN/GaN heterostructures: Application to double-barrier structures
Kristian Berland, Thorvald G Andersson, Per Hyldgaard
Inversion- and depletion-regions generally form at the interfaces between doped leads (cladding layers) and the active region of polar heterostructures like AlN/GaN and other nitri…
