1. Atomic and Electronic Structure of III-V Semiconductor Surfaces
Sammanfattning : The atomic and electronic structure of clean and Cs-perturbed III-V semiconductors was studied by angle-resolved photoelectron spectroscopy (ARPES), surface core level spectroscopy (SCLS), and scanning tunneling microscopy (STM). The work can be divided into three parts, dealing with low-index sur-faces, high-index surfaces, and special features of InAs. LÄS MER
2. Alkali Metal Adsorption on Metals Studied by Hiqh Resolution Core Level Spectroscopy and Low Energy Electron Diffraction
Sammanfattning : Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. LÄS MER
3. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection
Sammanfattning : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. LÄS MER
4. Surface structure and catalytic activity of Pd and Fe oxide surfaces and thin films
Sammanfattning : The present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO oxidation under semirealistic conditions.
