CUET Preparation Today
A p-type semiconductor can be obtained by adding |
arsenic to pure silicon aluminum to pure silicon phosphorous to pure germanium antimony to pure carbon |
aluminum to pure silicon |
The correct answer is Option (2) → aluminum to pure silicon A p-type semiconductor is created by adding a trivalent purity (such as aluminium) to a pure semiconductors like silicon. The trivalent impurity has one less valence electron than silicon, creating holes in the material. |
