  2. 1. Epitaxial growth of semiconductor nanowires

    Author : Ann Persson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; materialteknik; nanowires; nanostructures; growth mechanism; Materiallära; Material technology; Halvledarfysik; Semiconductory physics; nanoelectronics; Au; VSS; VLS; surface diffusion; band gap engineering; InP; ternary system; GaAs; heterostructures; InAs; CBE; epitaxy;

    Abstract : This thesis describes the results obtained from investigations carried out on epitaxially grown III-V semiconductor nanowires aimed at improving our understanding of and knowledge on the growth mechanism of nanowires. This is important to be able to control their growth, in order to make future applications possible. READ MORE

  4. 2. Optical Studies of Polytypism in GaAs Nanowires

    Author : Neimantas Vainorius; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photoluminescence; Raman scattering; Polytypism; Quantum confinement; GaAs nanowires; Fysicumarkivet A:2017:Vainorius;

    Abstract : Semiconductor nanowires are often regarded as having potential to be building blocks for novel applications. Their geometry allows defect-free combinations of materials that have a high degree of lattice mismatch. III-V semiconductor nanowires can also be grown in the wurtzite crystal phase, which is not stable in bulk material or thin films. READ MORE

  5. 3. Optical Spectroscopy of Single Nanowires

    Author : Johanna Trägårdh; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-shell nanowires; GaAs; InP; InAs; photocurrent; nanowire; time-resolved PL; photoluminescence; wurtzite;

    Abstract : This thesis describes optical spectroscopy on III-V semiconductor nanowires. The nanowires were grown by metal-organic vapor phase epitaxy (MOVPE) and chemical beam epitaxy (CBE). READ MORE

  6. 4. Doping of Semiconductor Nanowires

    Author : Jesper Wallentin; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; III-V semiconductor materials; nanowires; doping; solar cells; F:2013:Wallentin;

    Abstract : In this thesis, in situ doping during growth of III-V semiconductor nanowires, primarily for photovoltaic applications, is investigated. The nanowires were grown by metalorganic vapor phase epitaxy (MOVPE), with gold seed particles. READ MORE

  7. 5. Nanowires for Cell Research

    Author : Waldemar Hällström; Fasta tillståndets fysik; []
    Keywords : Nanotoxicology; Nanowires; Nanotubes; Nerve Cells; Cell Probing; Force Measurements; Nanotechnology; Axonal Guidance; Fysicumarkivet A:2010:Hällström;

    Abstract : This study explores the interaction between living biological cells and semiconductor nanowires. Biological cells are highly complex and dynamic entities, every one of them with individual characteristics and a high degree of internal and external communication. READ MORE
