This book consists of recent new developments in the field of ultrafast dynamics in semiconductors and nanostructures. It consists of eight chapters. Chapter 1 reviews spin dynamics in a high-mobility, two-dimensional electron gas. Chapter 2 deals with generation, propagation, and nonlinear properties of high-amplitude, ultrashort strain solitons in solids. Chapter 3 is devoted to nonlinear optical properties of nanoscaled artificial dielectrics. Chapter 4 discusses optical properties of hexagonal and cubic GaN self-assembled quantum dots. Chapter 5 reviews ultrafast, non-equilibrium electron dynamics in metal nanoparticles. Chapter 6 discusses the generation of monochromatic acoustic phonons in GaAs. Chapter 7 presents optical studies of carrier dynamics and non-equilibrium optical phonons in nitride-based semiconductors. Chapter 8 demonstrates electromagnetically induced transparency in semiconductor quantum wells.
There are many books on the market devoted to the review of certain fields. This book is different from those in that the 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 semiconductors and its device applications, as well as researchers and graduate students just entering the field, will benefit from it.
Editing a book with eight different chapters involving authors in several countries is not an easy task. I would like to thank all authors for their patience and cooperation. I would also wish to express appreciation to my wife and children for their encouragement, understanding, and support.
