A quantum-dot heat engine operating close to the thermodynamic efficiency limits
Martin Josefsson, Artis Svilans, Adam M. Burke +5
Cyclical heat engines are a paradigm of classical thermodynamics, but are impractical for miniaturization because they rely on moving parts. A more recent concept is particle-excha…
Nonlinear thermovoltage and thermocurrent in quantum dots
Sofia Fahlvik Svensson, Eric A Hoffmann, Natthapon Nakpathomkun +6
Quantum dots are model systems for quantum thermoelectric behavior because of the ability to control and measure the effects of electron-energy filtering and quantum confinement on…
Large nuclear spin polarization in gate-defined quantum dots using a single-domain nanomagnet
Gunnar Petersen, Eric A. Hoffmann, Dieter Schuh +3
The electron-nuclei (hyperfine) interaction is central to spin qubits in solid state systems. It can be a severe decoherence source but also allows dynamic access to the nuclear sp…
Heat flow in InAs/InP heterostructure nanowires
Jason Matthews, Eric A. Hoffmann, Carsten Weber +2
The transfer of heat between electrons and phonons plays a key role for thermal management in future nanowire-based devices, but only a few experimental measurements of electron-ph…
Lineshape of the thermopower of quantum dots
S. Fahlvik Svensson, A. I. Persson, E. A. Hoffmann +5
Quantum dots are an important model system for thermoelectric phenomena, and may be used to enhance the thermal-to-electric energy conversion efficiency in functional materials. It…
Mesoscopic Thermovoltage Measurement Design
E. A. Hoffmann, H. A. Nilsson, L. Samuelson +1
Quantitative thermoelectric measurements in the mesoscopic regime require accurate knowledge of temperature, thermovoltage, and device energy scales. We consider the effect of a fi…
