What are the different types of semiconductors?

There are two basic types of semiconductors; internal and outer. The material containing the inner semiconductor is generally pure. The outer semiconductor can be categorized as type N or P. This is the one to which dirt have been added to create the desired state. The N and P-Type semiconductors are external semiconductors to which different impurities have been added and subsequently have different conductive properties. Inner semiconductors are such materials with small or no dirt, silicon is most commonly used. The structure of the atomic grid of silicon crystals consists of perfect covalent bonds, which means that there are few free electrons. The crystal is almost insulator. As the temperatures rise above the absolute zero, the probability of the flow of the flow is the material. The process of adding certain dirt to semiconductors is referred to as doping. The added dirt is called Dopant. The amount of dopant added to the inner semiconductor proportionally changes the level of conductivity. The outer semiconductors are D ProductsOpping process.

Dopants are called either as acceptors or donors and changes the concentration of the hub carrier. There are two types of hub carriers in semiconductors; Free electron and hole where the electron was in the valence zone of the atom. The electron is a negative charge carrier and the hole is considered a positive carrier in the same size. Dopants have more valence zone electroning material that replaces more free electrons. Acceptor dopants have fewer valence zone electrons than the material it replaces and creates more holes.

The

n-type semiconductors are outer semiconductors in which donors were used. Results of the increase in negative electron charge carriers. Negative carriers are called the carrier of the majority in type N, while the carriers of positive cartridges are called a minority.

P-Typ semiconductors are the result of using the acceptor DOPANTat. As covalent bonds of the reform of the grid are left in the valence strips of the surrounding material. Increasing the holes increases the concentration of positive charge carriers. Most of the P -type carrier would be positive and minority negative.

Doping can be semiconductors with different and complementary conductive properties. An important application of this is the P-N intersection, where the P and N-Type semiconductors are narrow contact. One of the effects of the intersection is to combine holes and electrons and produce light. It is a light emitting diode (LED). The P-N connection also consists of a diode where electricity can flow in one direction through the intersection, but not in the other, a requirement for digital electronics.
