Which one of the following statement is false ?The resistance of intrinsic semiconductor decreases with increase of temperature.Pure Si doped with trivalent impurities gives a p-type semiconductor.Majority carriers in a n-type semiconductor are holesMinority carriers in a p-type semiconductor are electrons.

P-Type semiconductor has a lower electrical conductivity than N-Type semiconductor.(1 Point)TrueFalse

Dopingthe addition of small amounts of impuritiesdrastically affects its propertiessome materials form an excess of electrons andproduce an n-type semiconductorsome materials form an excess of holes andproduce a p-type semiconductorboth n-type and p-type materials have muchgreater conductivity than pure semiconductorsthis is extrinsic conduction

Choose the incorrect statement from the following:Semiconductors exhibit electrical properties between conductors and insulators.Electrical resistivity decreases with addition of impurities in semiconductors. Electrical conductivity decreases in semiconductors with increasing temperature. Examples of semiconductors include Germanium and Silicon.
