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.
