Quasi-conductors are considered to be a special kind of chemical elements. This class was discovered in early 1980’s but there were no required technologies to carry on the further researches. The research of semiconductors was continued only in the 1920’s. Russian scientists performed a lot of researches. The results showed that semiconductors can assist to accelerate the fluctuations and maintain them. During further years diodes were ejected by tubes. The most significant event in the history of semiconductor devices was the invention of the first transistor by Bell company in 1949. Since then many people all over the world become interested in such kind of matter as semiconductors.

The concern to optical characteristics of semiconductors revived due to discovery of induced emission in semiconductors. First laser system was developed with utilizing of semiconductors. The first version was based on p – n barriers, the latest ones – on heterojunction.

Nowadays we may see a huge amount of various pulsed power devices that operate with help of use of semiconductors. If there were no semiconductor systems used in the newest technologies, we won’t have a possibility to perform such nice researches that are important for other sciences.

Semiconductors are a wide class of matters that are characterized by the value of conductivity that is situated between the conductivities of metals and isolators. There are several elements that are mainly utilized to create the semiconductor devices. They are germanium, selenium, silicon, etc.

For quite long period of time semiconductors haven’t drawn the attention of physicists and engineers. Abram Ioffe is a Russian physicist who started performing different experiments in area of semiconductors. He noticed that this wonderful type of substance has got some special characteristics and described how they can be used. There are electron conduction and hole conduction developed by semiconductor devices. These features may be modified by usage of adding some admixtures or changing temperature. The admixtures influence significantly on the electron conduction of the semiconductors.

Almost every area of newest technologies implies use of semiconductors. Diodes, transistors and thyristors are the most often utilized systems. The wide application of semiconductors started not so long ago but today they are truly widely used. There is a possibility to transform almost every kind of energy into electric power by usage of semiconductors. With help of electricity they may create heat and cold. Semiconductor systems may be found in radio receiver and quantum generator, in little atomic battery and in microprocessors. Workers can’t do without semiconductor rectifiers, changers, disconnectors and amplifiers. The mass and size of semiconductor systems are considerably smaller than their tube analogues. When semiconductors are utilized some significant characteristics as power and reliability are being improved a lot.

There are a lot of different devices nowadays, that considerably ease our life and all these inventions appear only owing to the semiconductor systems.
