NEET Physics (general) Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Acceptor impurity (i) Creates holes in valence band (b) Pentavalent doping (ii) Introduces extra electrons (c) Majority carriers (iii) Formed in n-type semiconductor (d) Thermal excitation (iv) Increases temperature effects
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
Acceptor impurities, when added to a semiconductor, create holes in the valence band, while pentavalent doping introduces extra electrons, forming n-type semiconductors. Majority carriers are indeed electrons in n-type and holes in p-type semiconductors, and thermal excitation increases the carrier concentration with temperature.
