Question

Define semiconductor and doping​

Answer 1

Answer:

In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor.

Answer 2

Semiconductor

• In this case, the energy gap between the two bands is small.
• Some electrons may jump from Valence band to conduction band.
• These substances shows some conductivity.

Doping

• It's the process of introduction of impurity in the substance to inhance their conductivity.
• Doping is done in elements of group 14 like silicon, germanium, etc.
• Doping is done with electron deficient or electron rich elements like that of group 13 and group 15 respectively.
• It results in p- type and n - type semiconductor respectively.
