    Nyckelord :III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

    Sammanfattning : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

  3. 2. Properties of epitaxial lateral overgrowth of GaAsP and GaAs grown by hydride vapor phase epitaxy

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Lakshman Srinivasan; [2020]
    Nyckelord :GaAsP; ELOG; HVPE; Photoluminescence; Raman;

    Sammanfattning : Direct heteroepitaxy of III-Vs on silicon (Si) has always been a challenge and there are various strategies to integrate these materials. This thesis deals with one such strategy known as Epitaxial lateral overgrowth (ELOG) which is extensively supported by experiments. LÄS MER

  4. 3. The Influence of Oxygen on Nanowire Surface Structure and Electronic Properties

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Viktor Abelin; [2015]
    Nyckelord :Scanning tunneling microscopy; STM; Auger electron spectroscopy; AES; nanowire; hydrogen cleaning; Physics and Astronomy;

    Sammanfattning : This thesis investigates the possibilities for setups measuring how the surface structure of nanowires (NWs) influences their electric properties. For this the abilities to clean surfaces and detect nanowires (NWs) are examined, and an attempt to build a setup is made. LÄS MER
