Question

In a semiconductor laser the doping concentration is so high that tge fermi level in N type diode lies in

Answer 1

If a semiconductor is heavily doped than metal-insulator transition takes place and electron can easily jump without losing energy.

Explanation:

• If a semiconductor is heavily doped than the transition of metal-insulator transition takes place.
• In doping same type of atoms are arranged on each other in the form of layers and the electrons can easily move by jumping from one do-pant to another do-pant.
• In this way, the electron travels through long distances and move smoothly throughout the do-pant without losing their energy.
