  2. 11. Antimonide Heterostructure Nanowires - Growth, Physics and Devices

    Author : Mattias Borg; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GaSb; InSb; epitaxy; Nanowires; antimonides; tunnel field effect transistors; tunnel diode; InAsSb; Fysicumarkivet A:2012:Borg;

    Abstract : Abstract in UndeterminedThis thesis investigates the growth and application of antimonide heterostructure nanowires for low-power electronics. In the first part of the thesis, GaSb, InSb and InAsSb nanowire growth is presented, and the distinguishing features of the growth are described. READ MORE

  4. 12. Nanowires and Neural interfaces. Biocompatibility in the brain

    Author : Lina Gällentoft; NanoLund: Centre for Nanoscience; []
    Keywords : neural interface; neurons; BMI; nanowires; tissue responses; rat; biocompatibility; astrocytes; microglia;

    Abstract : Chronic neural interfaces that are able to record or stimulate neurons in the CNS are valuable instruments in use today and they hold great promise for the future both within neuroscience research and in the clinic. However, a major obstacle is that they show a decline in performance over time. READ MORE

  5. 13. Charge transport in III-V narrow bandgap semiconductor nanowires

    Author : Bekmurat Dalelkhan; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; InAs; InSb; InP-InAs; narrow bandgap; spin-orbit interaction; quantum dots; Nanowires; Fysicumarkivet A:2019:Dalelkhan;

    Abstract : This thesis describes charge transport in III-V narrow bandgap semiconductor nanowires. We are particularly interested in quantum transport in InSb, InAs and InP-InAs core-shell nanowires. According to the type of transport mechanism dominating in the devices, this thesis can be divided into four parts. READ MORE

  6. 14. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

    Author : Axel Persson; -lup-obsolete; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

    Abstract : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). READ MORE

  7. 15. Theory of electronic structure and transport in heterostructure nanowires

    Author : Florinda Viñas Boström; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electronic structure; electron transport; nano; quantum; InAs; GaSb; topological; nanowires; quantum dots; Fysicumarkivet A:2020:Vinas Boström;

    Abstract : Today, semi-conductor nanowires can be grown with very high precision, using epitaxy. This allows for studies of new nanowire-based quantum devices, likely to be part of novel quantum technologies in the future. This thesis concerns nanostructures based on InAs nanowires. READ MORE
