Directed Growth of Hydrogen Lines on Graphene: High Throughput Simulations Powered by Evolutionary Algorithm
G. Ozbal, J. T. Falkenberg, M. Brandbyge +2
We set up an evolutionary algorithm combined with density functional tight-binding (DFTB) calculations to investigate hydrogen adsorption on flat graphene and graphene monolayers c…
Grain boundary-induced variability of charge transport in hydrogenated polycrystalline graphene
Jose E. Barrios Vargas, Jesper T. Falkenberg, David Soriano +3
Chemical functionalization has proven to be a promising means of tailoring the unique properties of graphene. For example, hydrogenation can yield a variety of interesting effects,…
Localized electronic states at grain boundaries on the surface of graphene and graphite
Adina Luican-Mayer, Jose E. Barrios-Vargas, Jesper Toft Falkenberg +8
Recent advances in large-scale synthesis of graphene and other 2D materials have underscored the importance of local defects such as dislocations and grain boundaries (GBs), and es…
All-graphene edge contacts: Electrical resistance of graphene T-junctions
Kåre Wedel Jacobsen, Jesper Toft Falkenberg, Nick Papior +3
Using ab-initio methods we investigate the possibility of three-terminal graphene "T-junction" devices and show that these all-graphene edge contacts are energetically feasible whe…
