  1. 21. Fabrication of Low-Dimensional Structures in III-V Semiconductors

    Författare :Ivan Maximov; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; plasma; etching; aerosol; lithography; quantum dots; quantum well wires; quantum point contact; damage; luminescence; Fysicumarkivet A:1997:Maximov; Halvledarfysik; Semiconductory physics;

    Sammanfattning : The thesis presents studies on the processing technology and the characterization of nanometer-sized and low-dimensional structures in III-V semiconductors. Two major approaches are described: 1) the combination of aerosol technology and plasma etching for the fabrication of quantum dots (QDs) in InP-based materials and 2) the use of high-resolution electron beam lithography and plasma or wet chemical etching to make quantum well wires (QWWs) in both GaAs and InP-based structures.

  3. 22. Photoluminescence Studies of Single Quantum Dots

    Författare :Nikolay Panev; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stranski-Krastanow; photoluminescence; laser spectroscopy; antibunching; random telegraph noise; blinking; Physics; Fysik; Fysicumarkivet A:2004:Panev; solid immersion lens; quantum dots; low-dimensional structures;

    Sammanfattning : This thesis presents photoluminescence (PL) spectroscopy studies of single III-V semiconductor quantum dots (QDs). The electronic properties of the QDs, as well as, the dynamics of the processes taking part inside and in the surroundings of the QDs have been studied by single quantum dot photoluminescence spectroscopy, time resolved spectroscopy, and correlation spectroscopy.

  4. 23. Dynamics of Photogenerated Charge Carriers in III-V Bulk and Nanowire Semiconductors

    Författare :Xianshao Zou; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved spectroscopy; Group III-V semiconductor; Nanowires; Carrier recombination; Trapping; Passivation;

    Sammanfattning : As a solution to solving energy consumption and environment problems, photovoltaics has become one type of the promising devices to convert solar energy into electricity directly. In some special areas like in space, a kind of photovoltaics with lightweight and reliable properties is needed to supply power. LÄS MER

  5. 24. Nanowire Heterostructures- Growth, Characterization and Optical Physics

    Författare :Niklas Sköld; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Sammanfattning : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. LÄS MER
