Several papers review the recent success in materials preparation and in the remarkable structural and compositional control, especially for semiconductors and laser materials, but also for solid electrolytes. T h e o r y and experiment have greatly advanced the understanding o f p o i n t defects and t h e i r utilization for doping. Surfaces and interfaces are no l o n g e r just inevitable perturbations, instead they are used for quantization studies and device applications. The interaction with l i g h t remains a n active t o p i c ; solid laser sources as well as n o v e l optical characterization techniques are covered here. The manuscripts were s u b m i t t e d a t the meeting; only twelve weeks l a t e r this book is published, despite d o u b l e proof-reading. My compliments and t h a n k s t o publisher and a u t h o r s alike! This publication o f u p d a t e d reviews with a b u n d a n t reference to latest work - a t the speed o f a l e t t e rj o u r n a l - s h o u l d h o p e f u l l y b e n e f i t the solid state community. From next year on, the fun and excitement of editing this series goes to Joachim Treusch, the elected successor as chairman o f the semic o n d u c t o r division.
