16. Protective and Nanoporous Alumina Films Studied in situ by X-ray and Electrochemical Methods
Sammanfattning : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. LÄS MER
17. Using Light to Probe Surface Electrochemical Processes
Sammanfattning : This thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. LÄS MER

20. Excited state dynamics in low-dimensional perovskite nanocrystals
Sammanfattning : Two-dimensional (2D) perovskites have emerged as promising building blocks for optoelectronic applications. To fabricate high-performance devices, the relation between the material structures and their function in terms of excited state and charge carrier dynamics need to be well understood. LÄS MER
