Question
Chapter 21, Problem 21.22QP
Interpretation Introduction
Interpretation:
Silicon would form n-type semiconductors or p-type semiconductors with the given elements have to be explained.
Concept introduction:
n-type semiconductors in silicon: Solid semiconducting material having donor impurities are said to be n-type semiconductors, where “n” indicates negative which means the charge of the extra electron.
p-type semiconductors in silicon: Semiconducting material having acceptor impurities are said to be p-type semiconductors, where, ”p” indicates positive.
- Silicon atom has totally 14 electrons among them 4 electors are considered as valence electrons and these 4 valence electrons plays main role when an impurity added to it.
- The formation of n-type or p-type semiconductors is depending upon using impurities either pentavalent or trivalent.
