  1. 1. Non-local transport properties of a sextuple quantum dot system in the co-tunneling regime

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Fredrik Norrman Brange; [2014]
    Keywords : Quantum mechanics; Quantum entanglement; Bell s inequality; Nonlocal effects; Schrieffer-Wolff transformation; Full counting statistics; Physics and Astronomy;

    Abstract : Quantum entanglement between electrons in nanostructures is a key concept of quantum information still waiting to be experimentally demonstrated. In this master's thesis we present and analyze the full counting statistics of the charge transfer of a sextuple quantum dot system which works as both entangler and detector of spatially separated electrons.

  3. 2. Growth and characterization of Ge quantum dots on SiGe-based multilayer structures

    University essay from Institutionen för fysik, kemi och biologi

    Author : Andreas Frisk; [2009]
    Keywords : Ge dots; SiGe; Thermistor; IR-detector; Bolometer; intermixing; strain;

    Abstract : Thermistor material can be used to fabricate un-cooled IR detectors their figure of merit is the Temperature Coefficient of Resistance (TCR). Ge dots in Si can act as a thermistor material and they have a theoretical TCR higher than for SiGe layers but they suffer from intermixing of Si into the Ge dots. READ MORE

  4. 3. Structural and optical characterization of Si/Ge quantum dots

    University essay from Institutionen för fysik, kemi och biologi

    Author : Dan Wigblad; [2008]
    Keywords : quantum dot; IR detector; bolometer; semiconductor; germanium; silicon;

    Abstract : In this study silicon-germanium quantum dots grown on silicon have been investigated. The aim of the work was to find quantum dots suitable for use as a thermistor material. The quantum dots were produced at KTH, Stockholm, using a RPCVD reactor that is designed for industrial production. READ MORE
