What Does Word Semiconductor Mean and How Does It Work
June 25th, 2008 admin
Semiconductors are considered to be a special kind of chemical elements. Such class was discovered in early 1980's but there were no needed technologies to perform the further experiments. The analysis of semiconductors was continued only in the 1920's. The first successful research was performed by the Russian physicists in 1923. They proved that semiconductors may be utilized to accelerate fluctuations. During several years igct were ejected by tubes. The most significant event in the history of semiconductor devices was the creation of the first transistor by Bell corporation in 1949. That was the beginning of the epoch of semiconductor technologies.
Stimulated emission is really a quite interesting characteristic of semiconductors that has been discovered for several tens of years. By usage of such principles as p - n barriers and heterojunction physicists managed to create laser system in the beginning of the 60's.
