DEFINITION FOR DOPING
Back
DOPING
The method of adding impurities to a pure
semiconductor is known as DOPING, and the impurity added
is called the doping agent (e.g., Ar, Sb, P, Ge, and Al).

N – type semiconductor
When penta-valent impurity is added to the intrinsic semiconductors, n type semi conductors are formed When small amounts of penta-valent impurity such as phosphorous are added during crystal formation, the impurity
atoms lock into the crystal lattice

DEFINITION FOR SEMICONDUCTOR
Back
SEMICONDUCTOR
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. Common semiconductors include silicon and germanium.

APPLICATION OF DOPING IN SEMICONDUCTORS
Back
APPLICATION OF DOPING
Doping is used to enhance the electrical properties of semiconductors, allowing them to conduct electricity more effectively and enabling the creation of p-type and n-type materials.

EXAMPLES OF DOPING AGENTS
Back
DOPING AGENTS
Common doping agents include phosphorus (P) for n-type semiconductors and boron (B) for p-type semiconductors, which modify the electrical characteristics of the base material.
