  2. 1. Silicon δ-doping and Isoelectronic Doping in GaAs ans GaN Layers Grown by MBE

    Author : Jan Thordson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MBE; doping; GaN; III-V; delta-doping; heterostructures; GaAs;

    Abstract : This work concerns MBE-grown material, particularly physical effects due to controlled impurities of Si and N in arsenides, and the growth of nitrides and studies of Al- and As-impurities in them. Apart from interesting physical phenomena there are important device applications. The first part is devoted to studies of Si .delta. READ MORE

  4. 2. Characterization of Surfaces Relevant to Nanotechnology

    Author : Emelie Hilner; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; surface science; semiconductors; scanning tunneling microscopy; spectroscopic photoemission and low energy electron microscopy; low energy electron diffraction;

    Abstract : In this thesis investigations of the structure and dynamics of semiconductor surfaces relevant for the synthesis of nanostructures are presented. The studies were performed using Scanning Tunneling Microscopy (STM), Low Energy Electron Diffraction (LEED), and Spectroscopic PhotoEmission and Low Energy Electron Microcopy (SPELEEM). READ MORE
