  1. 16. Crystal Structures in GaAs Nanowires: Growth and Characterization

    Författare :Daniel Jacobsson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Jacobsson;

    Sammanfattning : With their nanometer size cross-section and high aspect ratio, semiconducting nanowires have properties that make them promising as building blocks in future electronic and optoelectronic devices. Because of their small size, their optical and electrical properties can differ from their bulk counterparts, and their geometry allows for material combinations not accessible in thin films.

  3. 17. Growth and characterization of SiC and GaN

    Författare :Rafal Ciechonski; Erik Janzén; Sebastian Lourdudoss; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiC; GaN; Deep level transient spectroscopy; Minority Carrier Transient Spectroscopy; Hall effect; Cathodoluminescence; Scanning electron microscopy; Atomic Force microscopy; sublimation growth; MOCVD; heterostructures; High Electron Mobility transistor; point defects; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : At present, focus of the SiC crystal growth development is on improving the crystalline quality without polytype inclusions, micropipes and the occurrence of extended defects. The purity of the grown material, as well as intentional doping must be well controlled and the processes understood. LÄS MER

  5. 19. Kinetic and thermodynamic modelling of ternary nanowire growth

    Författare :Egor Leshchenko; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductor materials; ternary nanowires; composition; crystal structure; modelling; Fysicumarkivet A:2021:Leshchenko;

    Sammanfattning : Among nanoscale structures of different shapes and dimensions nanowires are one of the most promising because of its truly unique properties different from their bulk counterparts. The energy quantization, perfect defect-free structure, and the possibility to grow them within the miscibility gap in combination with the benefits of bottom-up design and the possibility of integration on silicon substrates make nanowires ideal candidates for applications in optoelectronics, biotechnology and energy harvesting.
