The field of Si-based optoelectronics is greatly expanding and attracting increased interest from the scientific community. This interest is largely motivated by the possibility of combining, on the same substrate, the excellent data-processing performances of Si-based electronic functions with the unrivaled capability of light in the transmission of information. In fact, experimental efforts have led to several breakthroughs that promise new approaches and potential commercialization of low-cost Si-based photonic devices. Physical properties and optical performance of various materials (nanocrystals, porous Si, Er-doped Si and SiGe, to mention just a few examples) are now reasonably well understood, and the requirements necessary for efficient device performances have been elucidated. Experimental and theoretical contributions are presented here and topics include: Si-based integrated optoelectronics - state of the art and perspectives; waveguides and modulators; integrated and discrete light sources and detectors; properties and applications of silicon nanocrystals; materials for IR and visible light emission; and new materials and device concepts.
Presents 57 contributions from the fall 1997 symposium. Some of the most important conclusions to emerge from the papers are: Si-based visible and infrared light provide competing and complementary methods to overcome poor performance of Si as a light emitter; the silicon-on- insulator Si/SiO2/Si systems are ideal for highly confined waveguides and microphotonics components and for the fabrication of quantum wells and resonant tunneling structures; efficient integrated modulators and optically pumped amplifiers hold promise for Si-compatible optoelectronics; SiGe quantum wells, Ge films on buffered Si, and SnGe-alloys-upon-Si could be used for efficient near infrared light detection, once dark current problems are solved; and finally, new monolithic approaches to the engineering of the optical approaches of Si are allowing new applications and market space for low-cost Si-compatible integrated optoelectronics and microphotonics.

The evolution of Si-based optoelectronics has been extremely fast in the last few years and it is predicted that this growth will still continue in the near future. The aim of the volume is to present different Si-based luminescing materials as porous silicon, rare-earth doped silicon, Si nanocrystals, silicides, Si-based multilayers and silicon-germanium alloy or superlattice structures. The different devices needed for an all-Si-based optoelectronics are treated, ranging from light sources to waveguides, from amplifiers and modulators to detectors. Both the very basic treatments as well as applications to real prototype devices and integration in an optical integrated circuit are presented. Several issues are highlighted: the problem of electrical transport in low-dimensional Si systems, the possibility of gain in Si-based systems, the low modulation speed of Si-based LEDs. The book gives a fascinating picture of the state-of-the-art in Si microphotonics and a perspective on what one can expect in the near future.
The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.
Proceedings of a December 1997 symposium. Half of the 140 papers presented discuss various aspects of lithium batteries, especially modeling, synthesis, and processing of cathode materials. Other topics include rechargeable battery anode materials, intercalation and Li bonding sites, supercapacitors, the use of novel materials, new colloidal deposition techniques, and sol-gel processing procedures.

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.
Reports recent developments in a field that is coalescing but still lacks the coherence or certainty of a mature discipline in terms of accepted methodologies. The 39 papers discuss the resonance method as an attractive way to evaluate mechanical properties of thin gold films, heating effects on the Young's modulus of films sputtered onto micromachined resonators, test methods for characterizing piezoelectric thin films, polysilicon tensile testing with electrostatic gripping, silicon-based epitaxial films, and other aspects.

The 34 papers investigate the processing routes and properties of the complex molecular and macromolecular structures that hold biological cells together, both to reveal some of the mysteries of cell function and to identify natural solutions for optimizing membranes that might be adapted for applications in materials science. They cover the mechanics of DNA; the cytoskeleton, semiflexible polymers, polyelectrolytes, and motor proteins; properties and models of membranes and their interactions with macromolecules; biomaterials; and cells and cellular processes.
