Crossed graphene nanoribbons as beam splitters and mirrors for electron quantum optics
Sofia Sanz, Pedro Brandimarte, Géza Giedke +2
We analyze theoretically 4-terminal electronic devices composed of two crossed graphene nanoribbons (GNRs) and show that they can function as beam splitters or mirrors. These featu…
Theory of Spin-Dependent Electron Transfer Dynamics at Ar/Co(0001) and Ar/Fe(110) Interfaces
Moritz Müller, Pedro Miguel Echenique, Daniel Sánchez-Portal
Recent core-hole-clock experiments [Phys. Rev. Lett. , 086801 (2014)] showed that the spin dependence of electron injection times at Ar/Co(0001) and Ar/Fe(110) interf…
Electronic Properties of Substitutionally Boron-doped Graphene Nanoribbons on a Au(111) Surface
Eduard Carbonell-Sanromà, Aran Garcia-Lekue, Martina Corso +11
High quality graphene nanoribbons (GNRs) grown by on-surface synthesis strategies with atomic precision can be controllably doped by inserting heteroatoms or chemical groups in the…
A tunable electronic beam splitter realized with crossed graphene nanoribbons
Pedro Brandimarte, Mads Engelund, Nick Papior +3
Graphene nanoribbons (GNRs) are promising components in future nanoelectronics due to the large mobility of graphene electrons and their tunable electronic band gap in combination…
Electronic stopping power in a narrow band gap semiconductor from first principles
Rafi Ullah, Fabiano Corsetti, Daniel Sánchez-Portal +1
The direction and impact parameter dependence of electronic stopping power, along with its velocity threshold behavior, is investigated in a prototypical small band gap semiconduct…
Fully self-consistent and quasi-particle self-consistent for molecules
Peter Koval, Dietrich Foerster, Daniel Sánchez-Portal
Two self-consistent schemes involving Hedin's approximation are studied for a set of sixteen different atoms and small molecules. We compare results from the fully self-consis…
Dynamic screening and energy loss of antiprotons colliding with excited Al clusters
Natalia E. Koval, Daniel Sánchez-Portal, Andrey G. Borisov +1
We use time-dependent density functional theory to calculate the energy loss of an antiproton colliding with a small Al cluster previously excited. The velocity of the antiproton i…
