    Abstract : Semiconductor nanowires are studied by using transmission electron microscopy (TEM) based methods in this work. In the first section, the growth mechanism of gallium arsenide nanowires grown by chemical beam epitaxy is investigated. The nanowires are epitaxially grown from a gallium arsenide substrate by using gold seed particles as catalysts. READ MORE

    Abstract : This thesis describes the epitaxial growth of III-V semiconductor nanowires using Au seed particles, and the design of more complex three-dimensional branched structures from these wires. Growth was performed by metallorganic vapour phase epitaxy, in which precursor molecules for the semiconductor material components are introduced in a low-pressure vapour. READ MORE

  5. 5. From understanding to realizing novel III-Sb materials via nanowires

    Author : Luna Namazi; NanoLund; []
    Keywords : Fysicumarkivet A:2018:Namazi;

    Abstract : Due to their unique physical and material properties, III-Sb nanowires are considered good candidates for future devices, and test beds for understanding fundamental physics. Synthesizing these nanowires however is associated with certain challenging aspects, which are generally not present for other III-V nanowires, demanding the need for in depth investigations.
