One electron volt (eV)
2. At absolute zero temperature, semiconductor behaves as
Insulator
3. Define electrical conductivity.
Electrical conductivity is the ability to conduct an electric current.
4. What are the two types of charge carriers in semiconductors?
Electrons and holes are the two types of charge carriers in semiconductor.
5. Define charge carrier.
Charge carrier is a particle, which carries electric charge or electric current from one place to another place.
6. Define hole.
The absence of electron in the atomic shell is called a hole.
7. Define intrinsic semiconductors.
Pure semiconductors are called intrinsic semiconductors.

What are the minority charge carriers in p-type semiconductor?
Free electrons
29. Define generation and recombination of charge carriers.
Generation of charge carriers is the process by which free electrons and holes are generated as pairs.
Recombination of charge carriers is the process by which free electrons and holes are eliminated.
30. Define drift current.
Drift current is the electric current that flows through the semiconductor, when external voltage is applied.
31. Define diffusion current.
Diffusion current is the electric current caused by the charge carriers when they move from higher concentration region to the lower concentration region.
32. Define higher concentration region.
The region where large number of charge carriers is present is called higher concentration region.
33. Define lower concentration region.
The region where less number of charge carriers is present is called lower concentration region.
34. Define ohm’s law.
Ohm’s law states that, the electric current flowing through a material is directly proportional to the applied voltage and inversely proportional to the resistance of the material.
Ohm’s law is mathematically written as
I = V/R
Where, I = Electric current flowing through the
