  3. 3. Vertical III-V Semiconductor Devices

    Författare :Tomas Bryllert; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Halvledarfysik; Semiconductory physics; heterostructure barrier varactor frequency multiplier; field effect transistor; resonant tunneling; artificial molecule; terahertz; nanowire; Quantum dots;

    Sammanfattning : This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication. LÄS MER
