Current-induced runaway vibrations in dehydrogenated graphene nanoribbons
Rasmus Bjerregaard Christensen, Jing-Tao Lü, Per Hedegård +1
We employ a semi-classical Langevin approach to study current-induced atomic dynamics in a partially dehydrogenated armchair graphene nanoribbon. All parameters are obtained from d…
On the identification of pristine and defected graphene nanoribbons by phonon signatures in the electron transport characteristics
Rasmus B. Christensen, Thomas Frederiksen, Mads Brandbyge
Inspired by recent experiments where electron transport was measured across graphene nanoribbons (GNR) suspended between a metal surface and the tip of a scanning tunneling microsc…
Current-induced forces and hot-spots in biased nano-junctions
Jing-Tao Lü, Rasmus B. Christensen, Jian-Sheng Wang +2
We investigate theoretically the interplay of current-induced forces (CIF), Joule heating, and heat transport inside a current-carrying nano-conductor. We find that the CIF, due to…
Efficient calculation of inelastic vibration signals in electron transport: Beyond the wide-band approximation
Jing-Tao Lü, Rasmus B. Christensen, Giuseppe Foti +3
We extend the simple and efficient lowest order expansion (LOE) for inelastic electron tunneling spectroscopy (IETS) to include variations in the electronic structure on the scale…
Light emission and finite frequency shot noise in molecular junctions: from tunneling to contact
Jing-Tao Lü, Rasmus Bjerregaard Christensen, Mads Brandbyge
Scanning tunneling microscope induced light emission from an atomic or molecular junction has been probed from the tunneling to contact regime in recent experiments. There, the int…
Two routes to magnetic order by disorder in underdoped cuprates
R. B. Christensen, P. J. Hirschfeld, B. M. Andersen
We study disorder-induced magnetism within the Gutzwiller approximation applied to the t-J model relevant for cuprate superconductors. In particular, we show how disorder generates…
