Question
In a semiconductor crystal, if current flows due to breakage of crystal bonds, then the semiconductor is called
Correct Answer
Option C is the correct answer.
Detailed Explanation
In an intrinsic semiconductor, current flows due to the thermal generation of electron-hole pairs, which involves the breaking of crystal bonds. Extrinsic semiconductors (n-type or p-type) have impurities (donors or acceptors) added to increase the concentration of either electrons or holes, respectively, for conduction.
Hint
Consider the primary mechanism of charge carrier generation in pure, undoped semiconductors.
