Low temperature Kerr effect study of magnetic topological insulators and other magnetic structures
… using low energy electron microscopy (LEEM). A new approach is established to de-oxidise the surface of W(110) substrates at 1800 K, a temperature considerably lower than in the standard W(110) cleaning procedure (2100 K). LEEM also reveals the high-temperature dynamics of the Pt-Si …

Epitaxial graphene and cluster lattices on Iridium(111)
… have mainly been carried out with STM and LEEM in UHV. Graphene was grown by two basic methods:(i) Temperature programmed growth (TPG), which is adsorption of a carbon supplier, e.g. ethylene, at room temperature and the subsequent pyrolytic cleavage The morpholotgy is determined by the …

Solving norm equations over global function fields using compact representations
This thesis provides contributions to improving the efficiency of solving norm equations over global function fields F and providing theoretical and empirical evidence of the improvement. We present two new algorithms for solving norm equations over F; one is an exhaustive search algorithm inspired …

Interpreting Midway Barn: Understanding Frank Lloyd Wright's Agrarian Vision
At first glance, Midway Barn in Spring Green, Wisconsin presents itself as another example of Frank Lloyd Wright’s distinctive, if evolving style, its horizontal massing, tilted roof planes, and natural materials echoing the hilly landscape of the farm and its environs. Analysis of the documentary …

Growth and properties of metal-on-metal nanostructures: Ag on Cu(110) and Co on Ag(110)
Heteroepitaxial nanostructures have a diverse array of applications and show novel phenomena that arise from the exotic physics exhibited in reduced dimensions. We have investigated two nano-structured systems in order to gain insights into the dynamics of their nucleation, growth and have observed …
