  1. 1. Thermoelectric measurements on InAs nanowires with a ratchet-barrier

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

    Författare :Hanna Lundström; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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.
