Question

Which characteristic is typical of semiconductors?
Options
A They have very high electric conductivity, like metals.
B They have no free electrons and do not conduct electricity.
C They conduct little electricity when the temperature increases from zero Kelvin, but become good conductors when doped.
Correct Answer
D Their conductivity is always lower than insulators.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text explains: 'Such materials conduct little electricity when the temperature increases from zero Kelvin. When doped by the appropriate dopant, a semiconductor becomes a good conductor of electricity.' They are described as 'in-between conductors and insulators.'

Hint

Semiconductors are known for their adjustable conductivity.
