Excitonic valley effects in monolayer WS under high magnetic fields
Gerd Plechinger, Philipp Nagler, Ashish Arora +10
Transition-metal dichalcogenides can be easily produced as atomically thin sheets, exhibiting the possibility to optically polarize and read out the valley pseudospin of extremely…
Copper adatoms on graphene: theory of orbital and spin-orbital effects
Tobias Frank, Susanne Irmer, Martin Gmitra +2
We present a combined DFT and model Hamiltonian analysis of spin-orbit coupling in graphene induced by copper adatoms in the bridge and top positions, representing isolated atoms i…
Theory of proximity-induced exchange coupling in graphene on hBN/(Co, Ni)
Klaus Zollner, Martin Gmitra, Tobias Frank +1
We perform systematic first-principles calculations of the proximity exchange coupling, induced by cobalt (Co) and nickel (Ni) in graphene, via a few (up to three) layers of hexago…
Excitonic Stark effect in MoS monolayers
Benedikt Scharf, Tobias Frank, Martin Gmitra +3
We theoretically investigate excitons in MoS monolayers in an applied in-plane electric field. Tight-binding and Bethe-Salpeter equation calculations predict a quadratic Stark…
Theory of electronic and spin-orbit proximity effects in graphene on Cu(111)
Tobias Frank, Martin Gmitra, Jaroslav Fabian
We study orbital and spin-orbit proximity effects in graphene adsorbed to the Cu(111) surface by means of density functional theory (DFT). The proximity effects are caused mainly b…
