Semiconductor device | electronics | Britannica

Prior to the invention of the bipolar transistor in 1947, semiconductors were used only as two-terminal devices, such as rectifiers and photodiodes. During the early 1950s, germanium was the major semiconductor material. However, it proved unsuitable for many applications, because devices made of the material exhibited high leakage currents at only moderately elevated temperatures.

What is a Semiconductor? - thoughtco

A semiconductor is a material that has certain unique properties in the way it reacts to electrical current. It is a material that has much lower resistance to the flow of electrical current in one direction than in another. The electrical conductivity of a semiconductor is between that of a good conductor (like copper) and that of an insulator (like rubber).

Electronics Basics: What Is a Semiconductor? - dummies

Semiconductors are used extensively in electronic circuits. As its name implies, a semiconductor is a material that conducts current, but only partly. The conductivity of a semiconductor is somewhere between that of an insulator, which has almost no conductivity, and a conductor, which has almost full conductivity. Most semiconductors are crystals made of certain materials, [.]
