Silicon Nanophotonics

Leonid Khriachtchev graduated from Leningrad State University, Russia, in 1981. He completed his PhD study in Quantum Electronics in 1986 and became a Senior Scientist and a group leader in 1988 at the Institute of Physics of the same university. That time, his research mainly dealt with resonant light pressure and optical pumping of the ground state of atoms in the gas phase. In 1994, he joined the University of Helsinki, Finland, and he is currently with the Laboratory of Physical Chemistry of this university. His scientific interests include experimental optical and laser spectroscopy of matrix-isolated species and nanoscale materials. He has contributed to construction of new chemical bonds, including the first argon chemical compound, HArF, and light-induced conformational changes at low temperatures. Optical and structural studies of silicon nanocrystals have been another important part of this research activity. He is the editor of the book ""Silicon Nanophotonics: Basic Principles, Present Status, and Perspectives"" (Pan Stanford Publishing, 2008). He has authored over 180 refereed articles.

"Silicon Nanophotonics, edited by Leonid Khriachtchev, is a most useful and up-to-date collection of review articles covering the various aspects of silicon-based photonics, written by leading experts in the area. Both theoretical and experimental issues of silicon nanocrystals were considered, as well as device applications in both solid-state photonics and biology. This volume is an essential read for those working to make silicon shine as optoelectronics material."—Prof. Risto M. Nieminen, Helsinki University of Technology, Finland
