  1. 11. Epitaxial growth of Sn seeds and Sn-seeded InSb nanowires on InSb substrates

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Louise Laurenius; [2015]
    Keywords : nanoparticles; MOVPE; InSb nanowires; Technology and Engineering;

    Abstract : During the last decades, researchers have done extensive research on one-dimensional structures because of their promising properties for a broad range of applications. However, there are a few factors slowing down the process of integrating these nanowires in commercial products. To overcome this, new material combinations are being explored. READ MORE

  3. 12. Processing Technology for Si Based Tandem Solar Cells

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Nedim Aydinci; [2014]
    Keywords : ;

    Abstract : This project focuses on the investigation of Silicon based Tandem solar cell fabricated by using the Hydride Vapor Phase Epitaxy (HVPE). In the state-of-the-art multi-junction solar cell manufacturing epitaxial technologies are used for sub-cell formation, such as MOVPE (Metal Organic Vapour Phase Epitaxy) [1] or MBE (Molecular Beam Epitaxy) [2].

  4. 13. Cross-Sectional Scanning Tunneling Microscopy Studies of In 1-xGax Sb/InAs Quantum Dots

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Carl Reuterskiöld Hedlund; Christopher Ernerheim Jokumsen; [2012]
    Keywords : ;

    Abstract : This thesis focuses on the characterization of In 0,4 Ga 0,6 Sb/InAs and InSb/InAs quantum dots using Cross-Sectional Scanning Tunneling Microscopy (X-STM). Quantum dots (QDs) are small and spatially confined semiconductor nanostructures with a size-dependent band gap. READ MORE

  5. 14. Growth and structural characterization of GaP-GaPSb nanowires

    University essay from Lunds universitet/Atomfysik

    Author : Dario Stjärnemyr Ghidini; [2012]
    Keywords : Material Science; Nanowire; GaPSb; Physics and Astronomy; Chemistry; Technology and Engineering;

    Abstract : In this thesis epitaxial growth of Ga(P1-xSbx) and analysis by electron microscopy are presented. To the authors knowledge Ga(P1-xSbx)has not been grown in the form of nanowires before and the main motivation of this work is to investigate the possibility of overcoming the miscibility gap (1-99%) in nanostructures.

  6. 15. Comparison of Diffused and Implanted InSb pn-photodiodes Performance

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Ali Asadollahi; [2011]
    Keywords : ;

    Abstract : In this project, two different methods for fabrication of InSb p-n photodiodes were compared. Ion implantation with Mg as a standard way to fabricate InSb p-n diodes was compared to in-diffusion of zinc atoms from the gas phase using a metal organic vapor phase epitaxy (MOVPE) system.
