What are Semiconductors?
Semiconductors are materials that have electrical conductivity between that of conductors and insulators. Unlike conductors, which allow electrical current to flow freely, and insulators, which do not allow electrical current to flow at all, semiconductors have properties that lie somewhere in between.
Semiconductors can conduct electricity under certain conditions, but not under others. For example, semiconductors can conduct electricity when exposed to light, heat, or electrical fields. This property makes them ideal for use in a variety of electronic devices.

1. Bandgap
Semiconductors have a bandgap, which is the energy difference between the valence band and the conduction band. The valence band is the band of energy levels that are filled with electrons, while the conduction band is the band of energy levels that are empty or partially filled. The bandgap determines whether a material is a conductor, a semiconductor, or an insulator.

Doping is the process of intentionally adding impurities to a semiconductor material to modify its electrical properties. Doping can either increase or decrease the number of charge carriers (electrons or holes) in a semiconductor, thereby altering its conductivity.
