Optical Spectroscopy of Low Dimensional Semiconductors

This text covers basic physical aspects, novel technology and material fabrication tools, characterization methods and new devices, with special emphasis on quantum wire and quantum dot lasers. Advances in special epitaxial growth techniques, especially on patterned substrates, are remarkable, allowing the fabrication of well defined one- and zero-dimensional semiconductor systems. In addition to self-ordered quantum dots in a variety of materials other major topics include V-groove quantum wires, cleaved edge overgrowth, micro-cavities, electronic excitations in low dimensional systems, phonons and dissipative transport in nanostructures. Most of the papers cover III-V semiconductors, but Group IV and II-VI semiconductor microstructures are also covered. Theoretical papers are included on growth kinetics and the electronic properties of low dimensional structures, including many-particle effects.
