In the past, a number of Satellite Conferences have been held in con- nection with the International Conference on Physics of Semiconductors, covering selected fields of interest. In 1986, when the main conference was held in Stockholm, Sweden, new. phenomena had to be discussed: super- lattices, hot 'electron phenomena and new device structures for high-speed applications. The aim was to select topics which would be of interest to physicists as well as to electronics engineers. Therefore a Satellite Con- ference on H!gh-Speed Electronics, Basic Physical Phenomena and Device Principles, was arranged at Saltjobaden, a coastal resort near Stockholm. An organizing committee was established after the first suggestion made by Professor Grimmeiss from the University of Lund, Sweden, and some preliminary discussions on the Conference format. A Program Committee was established to be responsible for the further selection of the invited talks, the regular papers and poster presentation. The aim was to have a broad spectrum of contributions to attract physicists as well as device- oriented engineers and to stimulate discussions among the participants. These Proceedings contain all oral and poster presentations, with em- phasis on the invited talks, which give a competent overview of the field. The fast publication by Springer-Verlag has permitted the presentation of an up-to-date survey of the principles of high-speed electronics. Incorpo- ration in the Springer Series in Electronics and Photonics will enable the book to be distributed worldwide and to reach all interested scientists.
