Q: In a semiconductor, what is the term for the energy required to move an electron from the valence band to the conduction band?

Solution: The energy required to move an electron from the valence band to the conduction band is known as the band gap energy.

Steps: 5

Step 1: Understand that a semiconductor has two main energy bands: the valence band and the conduction band.
Step 2: The valence band is where electrons are normally present and is filled with electrons.
Step 3: The conduction band is where electrons can move freely and conduct electricity.
Step 4: To move an electron from the valence band to the conduction band, energy is needed.
Step 5: The amount of energy required to make this move is called the band gap energy.
