A general solution to the Schrödinger-Poission equation for charged hard wall: Application to potential profile of an AlN/GaN barrier structure
Kristian Berland
A general, system-independent formulation of the parabolic Schrödinger-Poisson equation is presented for a charged hard wall in the limit of complete screening by the ground state.…
Structure and binding in crystals of cage-like molecules: hexamine and platonic hydrocarbons
Kristian Berland, Per Hyldgaard
In this paper, we show that first-principle calculations using a van der Waals density functional (vdW-DF), [Phys. Rev. Lett. , 246401 (2004)] permits determination of…
Temperature stability of intersubband transitions in AlN/GaN quantum wells
Kristian Berland, Martin Stattin, Rashid Farivar +5
Temperature dependence of intersubband transitions in AlN/GaN multiple quantum wells grown with molecular beam epitaxy is investigated both by absorption studies at different tempe…
A van der Waals density functional study of adenine on graphite: Single molecular adsorption and overlayer binding
Kristian Berland, Svetla D. Chakarova-Kack, Valentino R. Cooper +2
The adsorption of an adenine molecule on graphene is studied using a first-principles van der Waals functional (vdW-DF) [Dion et al., Phys. Rev. Lett. 92, 246401 (2004)]. The cohes…
van der Waals density functional calculations of binding in molecular crystals
Kristian Berland, Oyvind Borck, Per Hyldgaard
A recent paper [J. Chem. Phys. 132, 134705 (2010)] illustrated the potential of the van der Waals density functional (vdW-DF) method [Phys. Rev. Lett. 92, 246401 (2004)] for effici…
