Radial etching of strongly confined crystal-phase defined quantum dots
Markus Aspegren, Chris Mkolongo, Sebastian Lehmann +3
We realize strongly confined quantum dots (QDs) in InAs nanowires (NWs) by combining epitaxial crystal-phase control with chemical wet etching. A strong axial confinement is first…

Information Thermodynamics in a Quantum Dot Szilard Engine - Experimentally Investigating Fluctuation Theorems and Thermodynamic Uncertainty Relations
David Barker, Sebastian Lehmann, Kimberly A. Dick +3
In Szilard's engine, measurement and feedback allows to extract work from an equilibrium environment, a process otherwise forbidden by the laws of thermodynamics. Recent theoretica…

Unconventional cross sections in zinc phosphide nanowires grown using exclusively earth-abundant components
Simon Escobar Steinvall, Hampus Thulin, Nico Kawashima +8
To enable lightweight and flexible solar cell applications it is imperative to develop direct bandgap absorber materials. Moreover, to enhance the potential sustainability impact o…
