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 (pure) semiconductor, current conduction occurs due to thermally generated electron-hole pairs. When crystal bonds break due to thermal energy, electrons become free to move (conduction band) and leave behind holes (valence band), both contributing to current flow. Doped semiconductors (n-type and p-type) have impurities added to increase the number of free charge carriers.
Hint
Consider the characteristics of pure semiconductors versus those with impurities.
