11. Antimonide Heterostructure Nanowires - Growth, Physics and Devices
Sammanfattning : 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. LÄS MER
12. Nanowires and Neural interfaces. Biocompatibility in the brain
Sammanfattning : 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. LÄS MER
13. Charge transport in III-V narrow bandgap semiconductor nanowires
Sammanfattning : 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. LÄS MER
14. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires
Sammanfattning : 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). LÄS MER
15. Theory of electronic structure and transport in heterostructure nanowires
Sammanfattning : 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. LÄS MER
