  1. 1. Properties of III-V/Si heterojunction fabricated by HVPE

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Prakhar Bhargava; [2020]
    Nyckelord :;

    Sammanfattning : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. LÄS MER

  3. 2. Rip off and characterization of nanowire ensembles for photovoltaic applications

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Sammanfattning : The main aim of this project was to peel off the epitaxially grown nanowires (NWs) from their native substrate and transfer them to the cheaper carrier substrate in order to make solar cell device from transferred NWs. Potentially the peeling and transferring idea is about to decrease the cost of NWs growth by reusing the native substrate especially for expensive material such as InP and GaAs which are suitable materials for single junction solar cell.

  4. 3. Optical studies of surface recombination velocity in 4H-SiC epitaxial layer

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Haniyeh Pourbagheri Mahabadi; [2011]
    Nyckelord :;

    Sammanfattning : In this work optical studies of the effect of surface passivation for surface recombination velocity at the interface between 4H-SiC epitaxial layer and various passivation layers are presented. Four samples have been used consisting of three main parts: thin film oxide layer, 4H-SiC epitaxial layer and 4H-SiC substrate. LÄS MER
