Semiconductors Diodes & Applications

Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of

• diode

• semiconductor

• conductor

• insulator

• superconductor

Doping of Semiconductors

• materials which can conduct electricity better than insulator, but not as well as conductors.

• The process of adding of a certain amount of specific impurities atoms in the pure semiconductor.

• when 4 electrons in outermost orbit.

what is the meaning of rectification?

• a process of smoothing using a capacitor

• a process of adding impurities to pure materials

• a process of converting an alternating current into a direct current by using a diode.
