Quasi-conductors are considered to be a special kind of chemical elements. In the first time that unique class was discovered in the 1890’s but more completely it started to be discovered just after the First World War in Europe and in Soviet Union. Russian physicists carried out lots of experiments. The results showed that semiconductors can help to generate the fluctuations and maintain them. There was no opportunity to create some sophisticated devices as igct. The most considerable event in the history of semiconductor devices was the invention of the first transistor by Bell corporation in 1949. That was the beginning of the era of semiconductor technologies.

A lot of scientists carry out a great deal of experiments simply to gain more knowledge about such characteristic of semiconductors as stimulated radiation. First laser device was created with utilizing of semiconductors. The first version was based on p - n barriers, the latest ones - on heterojunction.
