  4. 2. 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

  6. 4. Two-Dimensional Photonic Crystals in InP-based Materials

    Author : Mikaël Mulot; KTH; []
    Keywords : Photonic crystals; photonic bandgap materials; indium phosphide; dry etching; chemically assisted ion beam etching; reactive ion etching; electron beam lithography; photonic integrated circuits; optical waveguides; resonant cavities; optical filterin;

    Abstract : Photonic crystals (PhCs) are structures periodic in thedielectric constant. They exhibit a photonic bandgap, i.e., arange of wavelengths for which light propagation is forbidden. READ MORE

  7. 5. Fabrication of Low-Dimensional Structures in III-V Semiconductors

    Author : Ivan Maximov; Fasta tillståndets fysik; []
    Keywords : 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;

    Abstract : 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.
