  5. 3. Spectroscopic studies of III-V semiconductors in two, one and zero dimensions

    Author : Dan Hessman; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; InAs-InP; low-dimensional structures; quantum wells; quantum dots; quantum wires; k.p calculations; type-II; photoluminescence; V grooves; Stranski Krastanow; single dot spectroscopy; GaAs-InP; III-V semiconductors; Fysicumarkivet A:1996:Hessman; InAs-GaAs; GaInAs-InP; Halvledarfysik; InP-GaInP; Semiconductory physics;

    Abstract : In this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy.

  6. 4. Ion beam etching of InP based materials

    Author : Carl-Fredrik Carlström; KTH; []
    Keywords : InP; dry etching; ion beam etching; RIBE; CAIBE; hydrocarbon chemistry; trimethylamine; As P exchange reaction; morphology; low damage; AFM; SCM; annealing;

    Abstract : Dry etching is an important technique for pattern transferin fabrication of most opto-electronic devices, since it canprovide good control of both structure size and shape even on asub-micron scale. Unfortunately, this process step may causedamage to the material which is detrimental to deviceperformance. READ MORE

  7. 5. Epitaxial growth of semiconductor nanowires
