  1. 1. The Crystal Structure of III-V Semiconductor Nanowires: Growth and Characterization

    Author : Jessica Bolinsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; MOVPE; scanning tunneling microscopy; cathodoluminescence; XSTM; crystal structure; polytypism; III-V semiconductor materials; nanowires; Fysicumarkivet A:2010:Bolinsson;

    Abstract : This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. READ MORE

  2. 2. Growth of Semiconductor Nanowires for Solar Cell Applications

    Author : Magnus Heurlin; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MOVPE; Aerotaxy; III-V semiconductor materials; nanowire; solar cells; photovoltaics; Fysicumarkivet A:2015:Heurlin;

    Abstract : Nanowires have the ability to absorb light much more efficient than conventional thin film layers. This makes them candidates for the development of new types of solar cells that have higher efficiency and lower material usage than current technologies. READ MORE

  4. 4. Epitaxy of GaAs-based long-wavelength vertical cavity lasers

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Carl Asplund; KTH.; [2003]
    Keywords : gainnas; ingaas; quantum wells; movpe; mocvd; vertical cavity laser; bcsel; long-wavelength; epitaxy; xrd; dbr;

    Abstract : Vertical cavity lasers (VCLs) are of great interest aslow-cost, high-performance light sources for fiber-opticcommunication systems. They have a number of advantages overconventional edge-emitting lasers, including low powerconsumption, efficient fiber coupling and wafer scalemanufacturing/testing. READ MORE

  5. 5. Type-II interband quantum dot photodetectors

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Oscar Gustafsson; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; quantum dot; infrared; MOVPE; thermal imaging; type-II; photoluminescence; III V; InSb; InGaSb; InAs; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).
