Novel Transition-Metal Oxides Under Pressure
Transition-metal oxides have been the focus of multiple experimental and theoretical research efforts because of their versatility and applicability to new technology. These characteristics mostly owe to our ability to adjust valence states and crystal fields, among others, by fine-tuning …

Satellite Observations of Atmospheric Halogen Oxides
Die große Bedeutung von Halogenverbindungen bezüglich der Zerstörung atmosphärischen Ozons wurde schlagartig offenbar, als Mitte der Achtziger Jahre ein dramatischer Ozonverlust über der Antarktis beobachtet wurde, seither bekannt als Ozonloch. Während der folgenden Jahre konnten reaktive …

Interfacial Structures of Oxides on GaAs
For the deposited oxide/GaAs work, only deposition of (Ga,Gd)$\sb2$O$\sb3$ oxide among others shows a low interface trap density (D$\rm\sb{it})$ at the oxide-GaAs interface. It is low enough to warrant the demonstration of both n- and p-channel enhancement GaAs MOSFETs. High-resolution transmission …

Engineering Band Structures in Correlated Oxides
The electronic structure of short period digital superlattices of two different phases depends strongly on the superlattice architecture. We have fabricated digital superlattices of super cells consisting of N layers of LaMnO3 and N layers of SrTiO 3, N=1, 2, 3, 8, and measured their optical …

The Reactivity of Ditetrelenes Towards Organophosphorus Oxides
… tetramesityldigermene 5 towards organophosphorus oxides was explored in this thesis. The reaction of dialkyl and diarylphosphine oxides and phosphites with ditetrelenes 4 and 5 resulted in a 1,3-addition to form diorganodisilyl and digermyl phosphinites 27, 28, 31, 32 and disilyl phosphites 35 and …
