Technological advances in semiconductor growth has opened a broad horizon for semiconductor physics and applications during the past 20 years. High quality two-. dimensional systems are achieved with nearly atomic precision by direct epitaxial growth. Such structures led to novel applications like low noise high frequency modulation doped field effect transistors and quantum well lasers. Semiconductor heterostructures of lower dimensionality like quantum wires and quantum dots are not yet as mature, partly due to the lack in precision oflateral structuring technology. In recent years,...

Was sind die entscheidenden Faktoren für die Wirksamkeit von Erlebnispädagogik? Aufbauend auf grundlegenden Modellen entwickeln die Autor:innen des Buches eine neue Perspektive - sowohl aus Sicht der Teilnehmenden, als auch aus Sicht der durchführenden Erlebnispädagog:innen.Die Leser:innen werden für die Bedeutung einer möglichst neutralen und wertschätzenden Haltung sensibilisiert. Ziel ist, eine "echte" Entwicklung auf persönlicher Ebene bei den Teilnehmenden zu erreichen und diese zu begleiten. Viele Praxisbeispiele machen die theoretischen Überlegungen leicht verständlich.Die...

This book is the fifth in a series devoted to the theory and practice of inelastic light scattering (Raman and Brillouin) as applied to amorphous and crystalline solids. This volume is concerned with the investigation by these techniques of artificial periodic structures prepared by such gas-phase deposition techniques as Molecular Beam Epitaxy. The phenomena treated involve phonons, magnons, plasmons, and other electronic excitations. The book supplies theoretical background, information on modern experimental techniques such as multichannel detectors, and a number of experimental results.
