Answer:
Holes and Electrons in Semiconductors
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.

hi!
What are Semiconductors?
Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators (such ceramics). Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon.
Physics explains the theories, properties and mathematical approach governing the semiconductors. Semiconductors are a significant component of fundamental physics.
Examples of Semiconductors:
Gallium arsenide, germanium, and silicon are some of the most commonly used semiconductors. Silicon is used in electronic circuit fabrication, and gallium arsenide is used in solar cells, laser diodes, etc.
