1. 1. InAs and high-k oxides, a scanning tunnelling study of their interfaces

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Mattias Åstrand; [2018]
   Keywords : Semiconductor; High-k; Atomic layer deposition; Scanning tunnelling microscopy; Scanning tunnelling spectroscopy; Physics and Astronomy;

   Abstract : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. READ MORE

3. 2. Iron Oxide Thin Film Growth On Ag(100)

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Sara Ataran; [2014]
   Keywords : Surface Science; Material Science; XPS X-Ray Photoelectron Spectroscopy ; STM Scaning Tunneling Microscopy ; LEED Low Energy Electron Diffraction ; Science General;

   Abstract : This thesis presents a study of iron oxide thin films, grown on a silver metal substrate, with the goal of characterizing the structures that form during growth of the first atomic layers. Such ultra-thin iron oxides are interesting model materials for fundamental surface chemistry and catalysis studies. READ MORE
