Dynamical Variational Principles for Strongly Correlated Electron Systems
The self-energy-functional approach (SFA) is discussed in the context of different variational principles for strongly correlated electron systems.... -
Chemistry and Morphological Properties of Metal Interfaces to Organic Semiconductors
Metal contacts to organic semiconductors play a decisive role for the performance of organic based devices such as organic light emitting diodes,... -
Two-Gap Superconductivity in Magnesium Diboride
It is by now generally accepted that the recently discovered superconductor MgB2 is a superconductor with two energy gaps. Here we discuss how this... -
Atomic-Scale Properties of High-k Dielectrics: Ab Initio Study for Pr-Based Materials
We discuss the atomic and electronic structures and energetics of native point defects and of impurities (Si, Ti, B, moisture) in PrO1.5 and, to some... -
Dynamics of Membranes: From Passive to Active Systems
Fluid lipid membranes, which, together with filamentous proteins like actin, form the basic structural component of cells, have been a central topic... -
Intrinsic Spin Hall Effect
A brief review is given on a spin Hall effect, where an external electric field induces a transverse spin current. It has been recognized over 30... -
Sol-Gel Approaches to Photonic Crystal Systems
A prerequisite for an efficient ”molding the flow of light” by photonic crystals is the molding of materials in desired nanostructures. Very often,... -
Electron Spin Relaxation in Semiconductors
We review recent progress in the understanding of electron spin relaxation mechanisms in zinc-blende semiconductors. Increased spin lifetimes are... -
Materials Chemistry of Group 13 Nitrides
The OMVPE process has been used to grow thin films of group 13 nitrides, namely GaN, InN, and AlN. In recent years there has been a great deal of... -
