Physics 2010 JAMB Past Questions - Question 50: which of the following is a pure semiconductor ?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
A
Explanation
A pure semiconductor is a semiconductor material that is not intentionally doped with any impurities. In pure form, semiconductors like silicon and germanium have a very low concentration of charge carriers (electrons and holes), and their electrical conductivity is relatively low. They become more useful for electronic applications when they are doped with specific impurities to control their electrical properties.
So, a pure semiconductor could be either pure silicon (Si) or pure germanium (Ge). These are often used as the base material for many electronic devices and integrated circuits.
