  1. 1. Zeeman Interaction in Low-Dimensional III-V Semiconductor Structures

    Author : Bernhard Kowalski; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optically detected spin resonance; spin resonance; effective g-value; III-V semiconductors; low-dimensional structures; quantum wells; quantum dots; Stranski-Krastanow; photoluminescence; GaInAs; single dot Magneto-luminescence; Fysicumarkivet A:1997:Kowalski; Halvledarfysik; Semiconductory physics; GaInAs-InP;

    Abstract : The Zeeman interaction in low-dimensional III-V semiconductor nanostructures is studied. The effective g-value of bulk InGaAs is measured by two different spin resonance techniques. Experimental conditions were found to control the Overhauser effect, thus enabling a highly accurate determination of the g-value, g* = -4.070 ± 0. READ MORE

  2. 2. Magneto-optical studies of dilute nitrides and II-VI diluted magnetic semiconductor quantum structures

    Abstract : This thesis work aims at a better understanding of magneto-optical properties of dilute nitrides and II-VI diluted magnetic semiconductor quantum structures. The thesis is divided into two parts. The first part gives an introduction of the research fields, together with a brief summary of the scientific results included in the thesis. READ MORE

  3. 3. Optically detected magnetic resonance studies of intrinsic defects in dilute nitrides and SiC

    Author : Nguyen Quoc Thinh; Marek Godlewski; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Self-interstitials, vacancies and antisites belong to an important class of defects -intrinsic defects - in compound semiconductors. They have been found to be common occurring defects in semiconductor crystals grown under non-optimized or non-equilibrium conditions or subject to high-energy particle bombardment. READ MORE

  4. 4. Spin-dependent recombination in Ga(In)NAs alloys

    Author : Yuttapoom Puttisong; Weimin Chen; Irina Buyanova; Qingxiang Zhao; Linköpings universitet; []
    Keywords : ;

    Abstract : The abilities to control and manipulate electron spin, especially in semiconductors, lead to many interesting proposals for spin-functional devices in future spintronics and quantum information technology. A key requirement for the success of these proposals is that the spin functionality should be operational at room temperature (RT), which remains as a great challenge. READ MORE
