Answer #1
semiconductors allow only a little amount of light to pass through them. they are of two n-types n type and p type

Answer #2
Intrinsic semiconductor is a semiconductor without doping and by doping the intrinsic semiconductor to increase its conductivity,we get extrinsic semiconductor .

Answer #3
Intrinsic semiconducter are in which no external impurity is added.
Extrinsic semiconducter in which impurities added ..these are of two types p type (majority of holes) nd n type(majority of electrons)...

Answer #4
an intrinsic semiconductor is an undoped semiconductor. no impurities are added to it whereas extrinsic is the one which is doped with meatals and non metals to enhance the property

Answer #5
Intrinsic sc pure semiconductors. It has Fermi level at center of conduction band and valance band. Extrinsic sc are doped with acceptors and donors. Eg p type semiconductor and n type semiconductor. For p type semiconductor's Fermi level near to valance band and n type semiconductor's Fermi level near to conduction band.

Answer #6
Intrinsic semiconductors are highly pure semiconductors.
Extrinsic semiconductors have very less amount of impurities
