20 Examples of Semiconductor Materials

Semiconductor Materials

The conductivity refers to the capacity of a material or substance to let the electric current pass freely. The conductivity of a material depends fundamentally on its atomic and molecular structure. For example: Cadmium, Boron, Aluminum, Barium.

A material is conductive when, when it comes into contact with an electrically charged body, electricity is transmitted to all points on its surface. A conductive material offers little resistance to the passage of electricity. Electrons can circulate freely through it because they are loosely bound to the atoms and therefore they can conduct electricity. The best electric conductors are the metals.

Although all materials allow the conduction of electrical current to some degree, they are recognized as drivers to those who do it best, while, on the contrary, they will be insulators materials that do not allow electricity to pass through.

A material is semiconductor when it behaves either as a conductor or as an insulator, depending on the electric field in which it is found. It is not as good a conductor as metal, but it is not an insulator.

Types of semiconductors according to their purity

In order for a semiconductor to have greater conductivity, in addition to administering doping, the temperature.

Applications of semiconductor materials

Semiconductor materials have made it possible to create devices that replaced electronic tubes, generating a revolution in telecommunications due to its smaller size, the reduction of energy that its use implied and the decrease in cost.

The most important application for semiconductor materials is diodes. These electrical elements have the function of converting alternating current into direct current, a process known as rectification. Diodes are also used in solar panels, which convert the solar energy on electric, and as LED light emitters.
