   Sammanfattning : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. LÄS MER

3. 2. Optical Tweezers and Maxwell's Demon

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Författare :Markus Aspegren; [2016]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Future nanoscale applications of Brownian motors will benefit from further development of stochastic thermodynamics, bridging the the properties of systems in non-equilibrium with those in equilibrium. This thesis presents the first step towards a device mimicking Maxwell's demon, which will be used for a study of systems out of equilibrium. LÄS MER
