Tunable Current Rectification Through a Designer Graphene Nanoribbon
Niklas Friedrich, Jingcheng Li, Iago Pozo +2
Unimolecular current rectifiers are fundamental building blocks in organic electronics. Rectifying behavior has been identified in numerous organic systems due to electron-hole asy…
Pair excitations of a quantum spin on a proximitized superconductor
Stefano Trivini, Jon Ortuzar, Katerina Vaxevani +4
A magnetic impurity interacting with a superconductor develops a rich excitation spectrum formed by superposition of quasiparticles and spin states, which appear as Yu-Shiba-Rusino…
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…
Extending the spin excitation lifetime of a magnetic molecule on a proximitized superconductor
Katerina Vaxevani, Jingcheng Li, Stefano Trivini +4
Magnetic molecules deposited on surfaces are a promising platform to individually address and manipulate spins. Long spin excitation lifetimes are necessary to utilize them in quan…
Topological phase transition in chiral graphene nanoribbons: from edge bands to end states
Jingcheng Li, Sofia Sanz, Nestor Merino-Díez +7
Precise control over the size and shape of graphene nanostructures allows engineering spin-polarized edge and topological states, representing a novel source of non-conventional $π…
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…
