These proceedings contain the majority of papers presented atSymposium D, "Group IV heterostructures, physics and devices(Si,Ge,C,&agr;-Sn)", of the Spring Meeting of the EuropeanMaterials Research Society, held at the Congress Centre,Strasbourg, France, 4-7 June 1996. This Symposium was attendedby about 150 scientists from throughout the world, among whom 18were invited speakers.
The aim of the Symposium was to discussthe most recent results in all fields of Group IVheterostructures and devices from fundamental physics toindustrial applications. Regular and invited contributions werethen welcomed which addressed the different aspects of growth,the effects of strain relaxation, particularly in SiGeC alloys,the basic optical and electrical properties of heterostructuresand low-dimensional structures, the microelectronic andoptoelectronics, such as rare-earth doping techniques, was alsoselected. Except for minor changes, the order of papers presentedin this special issue of Thin Solid Films closely follows theorder of topics listed above as well as the order of sessions atthe Symposium.

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.

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, however, there was an enormous progress in novel epitaxial growth methods. This opens a wide new area of basic and applied semiconductor physics with the hope of novel applications in near future making use of the advantageous properties of one- and zero-dimensional systems. Ideas for future device applications mainly stem from the altered density of states being discrete or atomic-like for quantum dots. Optical spectroscopy has played and is playing a crucial role in the advancement of this fascinating field of semiconductor physics. The NATO school organized at Bilkent University in Ankara and in Antalya brought together experts in this field and newcomers, especially young Ph. D. students and postdocs, to learn about recent developments and to discuss open questions in the area of optical spectroscopy of low dimensional semiconductors. The school turned out to be extremely fruitful and there was a great enthusiasm among the lecturers and students during the whole two weeks.
