Ultrafast Spectroscopy of Semiconductors and Semiconductor Nanostructures Ultrafast spectroscopy of semiconductors is currently one of the most exciting areas of research in condensed-matter physics. Remarkable recent progress in the generation of tunable femtosecond pulses has allowed direct investigation of the most fundamental dynamical processes in semiconductors. This monograph presents some of the most striking recent advances in the field of ultrafast spectroscopy of semiconductors and their nanostructures. After a brief overview of the basic concepts and of the recent advances in the techniques of ultrashort pulse generation and ultrafast spectroscopy, it discusses the physics of relaxation, tunneling and transport dynamics in semiconductors and semiconductor nanostructures following excitation by femtosecond laser pulses.
