  4. 8. Transmission Electron Microscopy of III-V Nanowires and Nanotrees

    Författare :Lisa Karlsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Technological sciences; Naturvetenskap; Natural science; nanowires; TEM; III-V; Teknik;

    Sammanfattning : In this work, the morphology and crystal structure of epitaxial semiconductor nanowire structures grown by metal-organic vapour phase epitaxy (MOVPE) are studied by electron microscopy methods. In particular, the three-dimensional structure of nanowires and nanotrees has been characterised by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and multi-slice (MS) simulations.
