This book deals with optical properties of semiconductors at extremely short (pico- and femtosecond) time scales. The contributions, by an international roster of researchers, cover current research on a wide array of topics.Topics covered include: 1. Coherent Dynamics of Photoexcited Semiconductor Superlattices with Applied Homogeneous Electric Fields (Koch,Meier,Thomas) 2. Ultrafast non-equilibrium dynamics of intersubband excitations in quasi two dimensional semiconductors (Elsaesser,Woerner MPI Berlin) 3. Bloch-Oscillations in Semiconductors: Principles and Applications (Leo, TU Dresden) 4. Electron-velocity overshoot, electron ballistic transport and nonequilibrium phonon dynamics in nanostructure semiconductors (Tsen, Arizona State) 5. Coherent Control of Photocurrents in Semiconductors (Van Driel,Sipe U Toronto ) 6. Ensemble Monte Carlo Simulations of Ultrafast Phenomena in Semiconductors (Ferry & Goodnick, Arizona State) 7. Theory of Coherent Phonon Oscillations in Bulk GaAs (Stanton & Kuznetsov, U Florida) 8.Coherent Spectroscopy on Quantum Wires (Forchel, Bayer, & Bacher, U Wuerzburg) 9. The Vectorial Dynamics of Coherent Emission from Excitions (Smirl, U Iowa)

An international team of experts describes the optical and electronic properties of semiconductors and semiconductor nanostructures at picosecond and femtosecond time scales. The contributions cover the latest research on a wide range of topics. In particular they include novel experimental techniques for studying and characterizing nanostructure materials. The contributions are written in a tutorial way so that not only researchers in the field but also researchers and graduate students outside the field can benefit.

Pathogens such as viruses and bacteria are among the greatest threats to human health worldwide. In today's era of population growth and international travel, new technologies are desperately needed to combat the spread of known and emerging pathogens. This book presents a new concept for pathogen inactivation called selective photonic disinfection (SEPHODIS). The SEPHODIS technology inactivates pathogens by mechanical means, a total paradigm shift from traditional chemical and physical methods. The unique strength of SEPHODIS resides in its capability to inactivate pathogens while preserving desirable materials such as human cells and proteins. The technology also avoids the need to use chemicals, drastically reducing the risk of side effects. These properties make SEPHODIS ideal for important biomedical applications such as safeguarding blood products and therapeutics against pathogens, as well as producing effective and safe vaccines to combat infectious disease. Written in a style that is both technically informative and easy to comprehend for the layman reader, this book illustrates the story of SEPHODIS from its initial discovery and bench studies to its real-world applications.

There are many books in the market devoted to the review of certain fields. This book is different from those in that authors not only provide reviews of the fields but also present their own important contributions to the fields in a tutorial way. As a result, researchers who are already in the field of ultrafast dynamics in semicon ductors and its device applications as well as researchers and graduate students just entering the field will benefit from it. This book is made up of recent new developments in the field of ultrafast dynamics in semiconductors. It consists of nine chapters. Chapter 1 reviews a mi croscopic many-body theory which allows one to compute the linear and non-linear optical properties of semiconductor superlattices in the presence of homogeneous electric fields. Chapter 2 deals with ultrafast intersubband dynamics in quantum wells and device structures. Chapter 3 is devoted to Bloch oscillations in semicon ductors and their applications. Chapter 4 discusses transient electron transport phe nomena, such as electron ballistic transport and electron velocity overshoot phe nomena as well as non-equilibrium phonon dynamics in nanostructure semicon ductors. Chapter 5 reviews experimental and theoretical work on the use of the phase properties of one or more ultrashort optical pulses to generate and control electrical currents in semiconductors."
