Book Description
The articles in this book review recent developments in the microscopic theory of optical and electronic semiconductor properties. Many advances in this active field are intimately related to the work of Hartmut Haug and his coworkers. At the occasion of Haug's 60th birthday, a number of current and/or former members of his research team review the current state-of-the-art. Topics include the quantum kinetics of electrons, phonons and photons, coherent optical effects, quantum transport, ballistic motion, microscopic semiconductor laser theory with special emphasis on microlasers, symmetry aspects of laser excited semiconductors, as well as a review of the two-dimensional Wigner crystal in a strong magnetic field. The articles present the material in sufficient detail to be understandable by advanced graduate students and researchers who have a good background in quantum mechanics.

Book Description
During the last decades, semiconductors have become increasingly important for many technological applications due to their intriguing electronic properties. As an example, the conductivity of a semiconductors rises with increasing temperature which is opposite to the observations in metals. It is possible to modify the conductivity by the selective introduction of impurities. This so called doping allows for designing devices with well defined conduction properties like for example diodes or transistors. The invention of latter ones has been an important step in the development of modern computers. Unfortunately, the same physical processes that allow to design the electronic characteristics make semiconductor properties very sensitive to undesired impurities such that Wolfgang Pauli called semiconductor physics "dirt physics" in the 1920s. Today, modern epitaxy techniques allow to grow high-quality semiconductor devices with growth accuracies of one single atomic monolayer and a minimum of impurities. The origin of the interesting electronic properties of semiconductors is their special band structure. In contrast to conductors and similar to insulators, semiconductors have a filled valence band and an empty conduction band in the ground state. These bands are energetically separated by the band-gap energy. Compared to insulators, the band-gap energy is small (on the order of 1 eV) such that electrons can be excited from the valence band to the conduction band. The missing electrons in the valence band are often called holes and treated like quasi-particles that have opposite charge, spin and free-particle mass compared to the excited electrons. Depending on the structure of the semiconductor device and the environmental conditions, the electrons in the conduction band may act like the free electrons of a conductor and thus contribute to the conductivity. "Über Halbleiter sollte man nicht arbeiten, das ist eine Schweinerei, wer weiß ob es überhaupt.

Book Description
Primary goal of this book is to provide a cohesive description of the vast field of semiconductor quantum devices, with special emphasis on basic quantum-mechanical phenomena governing the electro-optical response of new-generation nanomaterials. The book will cover within a common language different types of optoelectronic nanodevices, including quantum-cascade laser sources and detectors, few-electron/exciton quantum devices, and semiconductor-based quantum logic gates. The distinguishing feature of the present volume is a unified microscopic treatment of quantum-transport and coherent-optics phenomena on ultrasmall space- and time-scales, as well as of their semiclassical counterparts.
