SEMICONDUCTORS



The term "Semiconductors" means "half-conductors", that is, a material the conductivity of which ranges between that of conductors and non-conductors (or insulators, as they are most of the time called by practicing power engineers). They include a great variety of basic elements (silicon, germanium, selenium, phosphorus and others), many chemical compounds and complexes (oxides, sulphides, etc.), as well as numerous ores and minerals.

While the conductivity of metals is very little influenced by temperature, the conductivity of semiconductors increases sharply with their heating, and it falls abruptly with their cooling. This co-relative dependence has opened great prospects for employing semiconductor in measuring instruments, that operate basing on recent scientific researches and mode
energy techniques. Light as well as heat increases the conductivity of semiconducting materials, this principle being used in creating photoresistances. It is also widely applied for switching on engines, for counting parts and single units on an automatic conveyer belt, as well as for various systems of emergency signals and for reproducing sound in cinematography. Besides reacting to light, semiconductors react to all kinds of radiations and are therefore employed in designing electronic counters.

Converting heat into electricity without using boilers or other machines and with little energy losses was one of the most complicated engineering problems that was faced by power researchers. This could be done by means of metal thermo-couples, which later on were made of semiconductors that generated ten times as much electricity as the metal ones.

Sunlight, like heat, wind or tide, can feed our electric circuits. Photocells made of semiconducting materials are capable of transforming ten per cent of sunray energy into electric power. By bu
ing wood, which has accumulated the same amount of solar energy, we obtain only fractions of one per cent of electric power, which is so much vital for our domestic and industrial purposes. The electricity generated by semiconductor thermocouples can produce not only heat but also cold, this principle being used in manufacturing cooling installations, including small-sized refrigerators.

Semiconductors are determining the progress of radio engineering, farm and industrial automation, some branches of chemistry, electrical engineering and many other fields of science and broader power installation design and application.
