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…
Quantized conductance and its correlation to the supercurrent in a nanowire connected to superconductors
Simon Abay, Daniel Persson, Henrik Nilsson +4
We report conductance and supercurrent of InAs nanowires coupled to Al-superconducting electrodes with short channel lengths and good Ohmic contacts. The nanowires are suspended 15…
Superconductor-Nanowire Devices from Tunneling to the Multichannel Regime: Zero-Bias Oscillations and Magnetoconductance Crossover
H. O. H. Churchill, V. Fatemi, K. Grove-Rasmussen +4
We present transport measurements in superconductor-nanowire devices with a gated constriction forming a quantum point contact. Zero-bias features in tunneling spectroscopy appear…
