Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
An electron and an electron hole are attracted to each other by electrostatic Coulomb
force and combine. This bound state of electron-hole pair is known as an exciton. It can carry
energy without transferring net electric charge because it is an electrically neutral quasiparticle. Excitons exist in semiconductors, insulators and some liquids. Frenkel exciton and
Wannier-Mott exciton are the two types of excitons. In this section, the origin of excitons, types
of excitons, and the relaxation and thermalization behavior of excitons with some research
results have been discussed.
