In particular, high-κ/InAs metal-oxide-semiconductor (MOS) structures and transport properties of GaSb nanowires have been studied. LÄS MER

  3. 2. Silicon nanowires, nanopillars and quantum dots : Fabrication and characterization

    Författare :Robert Juhasz; Jan Linnros; Philippe M. Fauchet; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon nanowires; silicon nanopillars; silicon quantum dots; size-reduction; thermal oxidation; electrochemical etching of silicon; photoluminescence; Semiconductor physics; Halvledarfysik;

    Sammanfattning : Semiconductor nanotechnology is today a very well studied subject, and demonstrations of possible applications and concepts are abundant. However, well-controlled mass-fabrication on the nanoscale is still a great challenge, and the lack of nanofabrication methods that provide the combination of required fabrication precision and high throughput, limits the large-scale use of nanodevices.

    Sammanfattning : Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter. LÄS MER
