Physics Question:

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

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

Answer #3Intrinsic 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 #4an 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 #5Intrinsic 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 #6Intrinsic semiconductors are highly pure semiconductors.
Extrinsic semiconductors have very less amount of impurities
