Semiconductor:
- Semiconductors are the materials that have a conductivity between conductors and insulators.
- Semiconductors are made of compounds such as gallium arsenide or pure elements, such as germanium or silicon.
- Holes and electrons are the types of charge carriers accountable for the flow of current in semiconductors.
- Holes (valence electrons) are the positively charged electric charge carrier whereas electrons are the negatively charged particles.
EXPLANATION:
- Intrinsic semiconductors are made of pure elements.
- Since no impurity is mixed in the intrinsic semiconductors, so the numbers of electrons and holes remain equal in an intrinsic semiconductor.
- Hence, option 1 is correct.
