Current-Controlled Negative Differential Resistance due to Joule Heating in TiO2
A. S. Alexandrov, A. M. Bratkovsky, B. Bridle +3
We show that Joule heating causes current-controlled negative differential resistance (CC-NDR) in TiO2 by constructing an analytical model of the voltage-current V(I) characteristi…
Gap opening in graphene by simple periodic inhomogeneous strain
I. I. Naumov, A. M. Bratkovsky
Using ab-initio methods, we show that the uniform deformation either leaves graphene (semi)metallic or opens up a small gap yet only beyond the mechanical breaking point of the gra…
Key pairing interaction in layered doped ionic insulators
A. S. Alexandrov, A. M. Bratkovsky
A controversial issue on whether the electron-phonon interaction (EPI) is crucial for high-temperature superconductivity or it is weak and inessential has remained one of the most…
Comment on ``Elastic Stabilization of a Single-Domain Ferroelectric State in Nanoscale Capacitors and Tunnel Junctions" [N.A. Pertsev and H. Kohlstedt, Phys. Rev. Lett. 98, 257603 (2007).]
A. M. Bratkovsky, A. P. Levanyuk
In a recent Letter [N.A. Pertsev and H. Kohlstedt, Phys. Rev. Lett. 98, 257603 (2007)] the authors claim that "even nanoscale capacitors and tunnel junctions may have out of plane…
Bistable molecular conductors with a field-switchable dipole group
P. E. Kornilovitch, A. M. Bratkovsky, R. S. Williams
A class of bistable "stator-rotor" molecules is proposed, where a stationary bridge (stator) connects the two electrodes and facilitates electron transport between them. The rotor…
Effects of gating and contact geometry on current through conjugated molecules covalently bonded to electrodes
A. M. Bratkovsky, P. E. Kornilovitch
We study the effects of gating and contact geometry on current through self-assembled monolayers of conjugated molecules strongly coupled to gold electrodes by sulfur ``anchor grou…
