Band Depopulation of Graphene Nanoribbons Induced by Chemical Gating with Amino Groups
Jingcheng Li, Pedro Brandimarte, Manuel Vilas-Varela +10
The electronic properties of graphene nanoribbons (GNRs) can be precisely tuned by chemical doping. Here we demonstrate that amino (NH) functional groups attached at the edges…
SIESTA: recent developments and applications
Alberto García, Nick Papior, Arsalan Akhtar +33
A review of the present status, recent enhancements, and applicability of the SIESTA program is presented. Since its debut in the mid-nineties, SIESTA's flexibility, efficiency and…
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…
Magnetism of topological boundary states induced by boron substitution in graphene nanoribbons
Niklas Friedrich, Pedro Brandimarte, Jingcheng Li +8
Graphene nanoribbons (GNRs), low-dimensional platforms for carbon-based electronics, show the promising perspective to also incorporate spin polarization in their conjugated electr…
Probing the magnetism of topological end-states in 5-armchair graphene nanoribbons
James Lawrence, Pedro Brandimarte, Alejandro Berdonces +5
We extensively characterize the electronic structure of ultra-narrow graphene nanoribbons (GNRs) with armchair edges and zig-zag termini that have 5 carbon atoms across their width…
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…
Doping of Graphene Nanoribbons via Functional Group Edge Modification
Eduard Carbonell-Sanromà, Jeremy Hieulle, Manuel Vilas-Varela +9
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone b…
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…
Search for a Metallic Dangling-Bond Wire on -doped H-passivated Semiconductor Surfaces
Mads Engelund, Nick Papior, Pedro Brandimarte +3
We have theoretically investigated the electronic properties of neutral and -doped dangling bond (DB) quasi-one-dimensional structures (lines) in the Si(001):H and Ge(001):H sub…
Bias-dependent local structure of water molecule at a metallic interface
Luana S. Pedroza, Pedro Brandimarte, Alexandre Reily Rocha +1
Understanding the local structure of water at the interfaces of metallic electrodes is a key problem in aqueous-based electrochemistry. Nevertheless, a realistic simulation of such…
