Low energy graphene edge termination via small diameter nanotube formation
Viktoria V. Ivanovskaya, Alberto Zobelli, Philipp Wagner +4
We demonstrate that free graphene sheet edges can curl back on themselves,reconstructing as nanotubes. This results in lower formation energies than any other non-functionalised ed…
Ripple edge engineering of graphene nanoribbons
Philipp Wagner, Christopher P. Ewels, Viktoria V. Ivanovskaya +3
It is now possible to produce graphene nanoribbons (GNRs) with atomically defined widths. GNRs offer many opportunities for electronic devices and composites, if it is possible to…
Behavior of hydrogen ions, atoms, and molecules in alpha-boron studied using density functional calculations
Philipp Wagner, Christopher P. Ewels, Irene Suarez-Martinez +4
We examine the behaviour of hydrogen ions, atoms and molecules in alpha-boron using density functional calculations. Hydrogen behaves as a negative-U centre, with positive H ions p…
