Bias, length, or coupling? What controls the quantum efficiency of electroluminescent single-polymers
Facundo Tarasi, Esteban D. Gadea, Tchavdar Todorov +1
Since the first evidence of luminescence of organic polymers in STM junctions, efforts have been invested in elucidating how to leverage the voltage, anchoring chemistry, and molec…
Viscous AC current-driven nanomotors
Vladimir U. Nazarov, Tchavdar N. Todorov, E. K. U. Gross
The recent discovery that electrons in nano-scale conductors can act like a highly viscous liquid has triggered a surge of research activities investigating consequences of this su…
Viscous current-induced forces
Vladimir U. Nazarov, Tchavdar N. Todorov, E. K. U. Gross
We study the motion (translational, vibrational, and rotational) of a diatomic impurity immersed in an electron liquid and exposed to electronic current. An approach based on the l…
Phonon and magnon jets above the critical current in nanowires with planar domain walls
Maria Stamenova, Plamen Stamenov, Tchavdar Todorov
We show through non-equilibrium non-adiabatic electron-spin-lattice simulations that above a critical current in magnetic atomic wires with a narrow domain wall (DW), a couple of a…
Towards temperature-induced topological phase transition in SnTe: A first principles study
José D. Querales-Flores, Pablo Aguado-Puente, Đorđe Dangić +6
The temperature renormalization of the bulk band structure of a topological crystalline insulator, SnTe, is calculated using first principles methods. We explicitly include the eff…
Thermal conductivity of porous polycrystalline PbTe
Javier F. Troncoso, Piotr Chudzinski, Tchavdar N. Todorov +3
PbTe is a leading thermoelectric material at intermediate temperatures, largely thanks to its low lattice thermal conductivity. However, its efficiency is too low to compete with o…
