A thorough reference work bridging the gap between contemporary and traditional approaches to noise problems Noise in semiconductor devices refers to any unwanted signal or disturbance in the device that degrades performance. In semiconductor devices, noise is attributed to hot-electron effects. Current advances in information technology have led to the development of ultrafast devices that are required to provide low-noise, high-speed performance. Microwave Noise in Semiconductor Devices considers available data on the speed versus noise trade-off and discusses optimal solutions in semiconductors and semiconductor structures. These solutions are of direct interest in the research and develo...
les Houches This Winter School on "The Physics and Fabrication of Microstructures" originated with a European industrial decision to investigate in some detail the potential of custom-designed microstructures for new devices. Beginning in 1985, GEC and THOMSON started a collaboration on these subjects, supported by an ESPRIT grant from the Commission of the European Com munity. To the outside observer of the whole field, it appears clear that the world effort is very largely based in the United States and Japan. It also appears that cooperation and dissemination of results are very well organised outside Europe and act as a major influence on the development of new concepts and devices. In Japan, a main research programme of the Research and Development for Basic Technology for Future Industries is focused on "Future Electron Devices". In Japan and in the United States, many workshops are organised annually in order to bring together the major specialists in industry and academia, allowing fast dissemination of advances and contacts for setting up cooperative efforts.
Noise in physical systems - as a consequence of the corpuscular nature of matter - conveys information about microscopic mechanisms determining the macroscopic behavior of the system. Besides being a source of information, noise also represents a source of annoying disturbances which affect information transMission along a physical system. Therefore, noise analysis can promote our insight into the behavior of a physical system, as well as our knowledge of the natural constraints imposed upon physical-information transmission channels and devices. In recent years the continuous scientific and technical interest in noise problems has led to a remarkable progress in the understanding of noise p...
Provides an overview of the physical basis of noise in semiconductor devices, and a detailed treatment of numerical noise simulation in small-signal conditions. It presents innovative developments in the noise simulation of semiconductor devices operating in large-signal quasi-periodic conditions.
Compound semiconductor devices form the foundation of solid-state microwave and optoelectronic technologies used in many modern communication systems. In common with their low frequency counterparts, these devices are often represented using equivalent circuit models, but it is often necessary to resort to physical models in order to gain insight into the detailed operation of compound semiconductor devices. Many of the earliest physical models were indeed developed to understand the 'unusual' phenomena which occur at high frequencies. Such was the case with the Gunn and IMPATI diodes, which led to an increased interest in using numerical simulation methods. Contemporary devices often have f...
The area of high field transport in semiconductors has been of interest since the early studies of dielectric breakdown in various materials. It really emerged as a sub-discipline of semiconductor physics in the early 1960's, following the discovery of substantial deviations from Ohm's law at high electric fields. Since that time, it has become a major area of importance in solid state electronics as semiconductor devices have operated at higher frequencies and higher powers. It has become apparent since the Modena Conference on Hot Electrons in 1973, that the area of hot electrons has ex tended weIl beyond the concept of semi-classical electrons (or holes) in homogeneous semiconductor mater...

The volume constitutes the proceedings of the 13th International Conference on Noise in Physical Systems and 1/f Fluctuations (ICNF'95) held in Palanga, Lithuania, in the period 29 May - 3 June 1995.International conference of fluctuation phenomena has a rich history. Previous ones were held in St. Louis (USA, 1993), Kyoto (Japan, 1991), Budapest (Hungary, 1989), Montreal (Canada, 1983), etc. The conference proved to be successful in bringing together specialists in fluctuation phenomena in very different areas, and providing a bridge linking theorists and applied scientists involved in the design of new generation of electronic devices. Correspondingly, the volume covers fundamental aspects of noise in various fields of science and modern technology. Mesoscopic fluctuations, noise in high temperature superconductors, in nanoscale structures, in optoelectronic and microwave devices, fluctuation phenomena in biological systems and human body are in the spotlight.
Much has been learned about the subject of noise and random fluctuations over the last 170 years (some old milestones: Brownian motion, 1826; Einstein's diffusion theory, 1905; Johnson-Nyquist thermal noise, 1926), but much remains to be known. This volume will be interesting reading for physicists, engineers, mathematicians, biologists and PhD students. The invited papers in the volume survey classical unsolved problems while the regular papers present new problems and paradoxes.
