Mach--Zehnder-like interferometry with graphene nanoribbon networks

Sofia Sanz, Nick Papior, Géza Giedke +3

We study theoretically electron interference in a Mach--Zehnder-like geometry formed by four zigzag graphene nanoribbons (ZGNRs) arranged in parallel pairs, one on top of the other…

Addressing electron spins embedded in metallic graphene nanoribbons

Niklas Friedrich, Rodrigo E. Menchon, Iago Pozo +7

Spin-hosting graphene nanostructures are promising metal-free systems for elementary quantum spintronic devices. Conventionally, spins are protected from quenching by electronic ba…

Spin-polarizing electron beam splitter from crossed graphene nanoribbons

Sofia Sanz, Nick Papior, Géza Giedke +3

Junctions composed of two crossed graphene nanoribbons (GNRs) have been theoretically proposed as electron beam splitters where incoming electron waves in one GNR can be split cohe…

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…

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…
