The 15th International Conference on Nonequilibrium Carrier Dynamics in Semiconductors (HCIS15) will be held in Tokyo, Japan, from July 23 (Mon) through 27 (Fri), 2007. Since the first meeting was held in Modena, Italy, in 1973, this series of meetings have been organized regularly; Modena, Italy (1973), Denton, USA (1977), Montpellier, France (1981), Innsbruck, Austria (1985), Boston, USA (1987), Scottsdale, USA (1989), Nara, Japan (1991), Oxford, UK (1993), Chicago, USA (1995), Berlin, Germany (1997), Kyoto, Japan (1999), Santa Fe, USA (2001), Modena, Italy (2003), and Chicago, USA (2005).

The purpose of HCIS is to provide an international forum on the latest progress in the field of physics and applications of nonequilibrium carrier dynamics in bulk semiconductors, nanostructures, and structures of molecular scales.
