Direct Mapping of Local Seebeck Coefficient in 2D Material Nanostructures via Scanning Thermal Gate Microscopy
Achim Harzheim, Charalambos Evangeli, Oleg V. Kolosov +1
Local variations in the Seebeck coefficient in low-dimensional materials-based nanostructures and devices play a major role in their thermoelectric performance. Unfortunately, curr…
Single-Material Graphene Thermocouples
Achim Harzheim, Fabian Könemann, Bernd Gotsmann +2
On-chip temperature sensing on a micro- to nanometer scale is becoming more desirable as the complexity of nanodevices and size requirements increase and with it the challenges in…
A Mechanically Tunable Quantum Dot in a Graphene Break Junction
Sabina Caneva, Matthijs D. Hermans, Martin Lee +7
Graphene quantum dots (QDs) are intensively studied as platforms for the next generation of quantum electronic devices. Fine tuning of the transport properties in monolayer graphen…
Efficient heating of single-molecule junctions for thermoelectric studies at cryogenic temperatures
Pascal Gehring, Martijn van der Star, Charalambos Evangeli +4
The energy dependent thermoelectric response of a single molecule contains valuable information about its transmission function and its excited states. However, measuring it requir…
Tunneling spectroscopy of localized states of barriers in vertical van der Waals heterostructures
Nikos Papadopoulos, Pascal Gehring, Kenji Watanabe +3
In transition metal dichalcogenides, defects have been found to play an important role, affecting doping, spin-valley relaxation dynamics, and assisting in proximity effects of spi…
The role of metallic leads and electronic degeneracies in thermoelectric power generation in quantum dots
Achim Harzheim, Jakub K. sowa, Jacob L. Swett +3
The power factor of a thermoelectric device is a measure of the heat-to-energy conversion efficiency in nanoscopic devices. Yet, even as interest in low-dimensional thermoelectric…
