1. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER
2. Femtosecond Photoemission Electron Microscopy of Indium Arsenide Nanowires
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : PhotoEmission Electron Microscopy (PEEM) has proven to be a successful method for examining the electronic characteristics of nanostructures. The experiments relevant for the following report were conducted using a combination of PEEM and a femtosecond pulsed laser to determine the electrical characteristics of Indium Arsenide nanowire of crystal structure varying between wurtzite and zinc blend.

3. Electrical and Optical Characterization of InAsP/InP Nanowire-Based Avalanche Photodetectors
Magister-uppsats, Högskolan i Halmstad/FotonikSammanfattning : The availability of new manufacturing methodology in solid state physics makes it possible to grow nano-photonic devices for better performance and unique properties. In this thesis work, we use I-V and FTIR spectroscopy to study the electrical and optical properties of InAsP/InP nanowire-based array avalanche photodetectors for near infrared applications. LÄS MER
4. Infuence of surface and crystal structure on the conductivity of individual InAs and InP nanowires
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : To satisfy the great need for (opto-)electronic devices to become smaller and more efficient in energy and price, research is done on semiconducting III-V nanowires (NWs). Electrical devices using NWs show noteworthy assets being fast-paced with high-speed electronics and low power consumption, one of which are high-efficient solar cells at a moderate price. LÄS MER
