Question

The energy gap between conduction and valence bands of silicon is:

• A. 5.4 eV
• B. 1.1 eV
• C. 0.7 eV
• D. 1.4 eV

Hint:

For semiconductors like silicon, the energy gap plays a significant role in determining their electrical conductivity. A smaller band gap allows electrons to easily move from the valence band to the conduction band.

Answer 1

The Correct Option is B

The energy gap between the conduction and valence bands of silicon is approximately 1.1 eV. This is the band gap energy that separates the energy levels of the electrons in the valence band from those in the conduction band. Silicon is a semiconductor, and the value of the band gap is critical for determining its electrical properties.
Thus, the correct answer is 1.1 eV.
