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…

Measuring Temperature Gradients over Nanometer Length Scales
E. A. Hoffmann, H. A. Nilsson, J. E. Matthews +4
When a quantum dot is subjected to a thermal gradient, the temperature of electrons entering the dot can be determined from the dot's thermocurrent if the conductance spectrum and…

Quantum-dot thermometry
E. A. Hoffmann, N. Nakpathomkun, A. I. Persson +3
We present a method for the measurement of a temperature differential across a single quantum dot that has transmission resonances that are separated in energy by much more than th…
