Gate-tunable nonreciprocal thermoelectric effects on the surface states of topological insulators
Phillip Mercebach, Sun-Yong Hwang, Bo Lu +3
Thermoelectric devices at the nanoscale offer promising routes for on-chip refrigeration and waste-heat recovery, yet most semiconductor-based implementations suffer from limited t…
Statistical analysis of electron-induced switching of a spin-crossover complex
Jonas Fußangel, Björn Sothmann, Sven Johannsen +5
Spin-crossover complexes exhibit two stable configurations with distinct spin states. The investigation of these molecules using low-temperature scanning tunneling microscopy has o…
Phase-controlled heat modulation with Aharonov-Bohm interferometers
Sun-Yong Hwang, Björn Sothmann, Rosa López
A heat modulator is proposed based on a voltage-biased Aharonov-Bohm interferometer. Once an electrical bias is applied, Peltier effects give rise to a flow of heat that can be mod…
Nonlocal thermoelectric detection of interaction and correlations in edge states
Alessandro Braggio, Matteo Carrega, Björn Sothmann +1
We investigate nonequilibrium effects in the transport of interacting electrons in quantum conductors, proposing the nonlocal thermoelectric response as a direct indicator of the p…
Dimer Coupling Energies of the Si(001) Surface
Christian Brand, Alfred Hucht, Giriraj Jnawali +6
The coupling energies between the buckled dimers of the Si(001) surface were determined through analysis of the anisotropic critical behavior of its order-disorder phase transition…
Superconductor-quantum dot hybrid coolers
Sun-Yong Hwang, Björn Sothmann, David Sanchez
We propose a refrigeration scheme in a mesoscopic superconductor-quantum dot hybrid device. The setup can significantly cool down a normal metal coupled to the device by applying a…
