1. Thermoelectric measurements on InAs nanowires with a ratchet-barrier
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikAbstract : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.

2. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
University essay from KTH/Tillämpad fysikAbstract : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. READ MORE

3. Finite element modelling of strained nanowire heterostructures
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE
