A semiconductor material is one that has intermediate electrical conductivity between conductors and insulators. Unlike conductor materials, electrons in semiconductors do not move easily.
However, by applying an external voltage or energy, it is possible to control their conductivity.
This is achieved by adding impurities or dopants to the material, which modifies the amount of electrons available to conduct electric current.
Semiconductors are essential in the manufacturing of electronic components such as transistors, diodes, and integrated circuits, which form the basis of modern technology.
