The process by which impurity is introduced in semiconductors to enhance its conductivity is known as ____________.
Electrical conductivity of semiconductors increases with increase in ____________.
Why does the electrical conductivity of semiconductors increase with rise in temperature?
Assertion: Semiconductors are solids with conductivities in the intermediate range from 10–6 – 104 ohm–1m–1.
Reason: Intermediate conductivity in semiconductor is due to partially filled valence band.
