semiconductor Quiz Practice Quiz | semiconductor

Q: Which of the following describes the behavior of a semiconductor material when exposed to an increase in temperature?

The conductivity increases. — Temperature increase causes more electrons to jump to the conduction band, increasing conductivity.

Q: What is the primary function of doping in a semiconductor material?

To increase the concentration of charge carriers. — Doping introduces impurities, creating either excess electrons (n-type) or holes (p-type), thereby increasing carrier concentration.

Q: What type of semiconductor is formed when a pentavalent impurity is added to a pure silicon crystal?

N-type semiconductor — Pentavalent impurities have 5 valence electrons, providing extra electrons and creating an n-type semiconductor.

Q: Which of the following is NOT a common application of semiconductors?

Resistors — Resistors are typically made of materials that offer a specific resistance value, not relying on semiconductor properties.

Q: What is the depletion region in a p-n junction?

A region depleted of free charge carriers. — The depletion region is devoid of free charge carriers due to the diffusion and recombination processes at the junction.
