1. Electronic effects at metallic surfaces and interfaces : image-state formation and charge redistribution
Sammanfattning : .... LÄS MER
2. Hydrogen in metallic thin films, multilayers and superlattices
Sammanfattning : .... LÄS MER
3. Magnetism of Semiconductors and Metallic Multilayers
Sammanfattning : Magnetic properties of diluted magnetic semiconductors and magnetic metallic multilayers are investigated by SQUID magnetometry. By doping GaAs with magnetic Mn2+ ions under well defined growth conditions, one obtains a diluted magnetic semiconductor, (Ga,Mn)As, in which the randomly-distributed magnetic ions act as acceptor centers.

4. Phase Transitions and Phase Formation of Hydrogen in Quasi-2D Lattices
Sammanfattning : The role of the dimensionality and strain state of metallic lattices on the phase behavior of dissolved hydrogen was explored. Metallic superlattices with well defined hydrogen absorption potential on the nm scale, were utilized as test systems. LÄS MER
5. Influence of Self-trapping, Clamping and Confinement on Hydrogen Absorption
Sammanfattning : The dissociation of hydrogen molecules at surfaces is the first step in the absorption process. If the absorbing material is covered by an oxide, this layer will determine the effective uptake rate of an underlying absorbing material. LÄS MER
