Question:
The band gap energy of silicon is
The band gap energy of silicon is
Show Hint
Silicon (1.1 eV) is widely used in semiconductors due to moderate band gap.
Updated On: Apr 24, 2026
- \(1.1 \, eV\)
- \(0.7 \, eV\)
- \(1.7 \, eV\)
- \(2.1 \, eV\)
- \(0.5 \, eV\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Band gap energy is the energy difference between valence band and conduction band.
Step 1: Recall standard values.
• Silicon $\rightarrow$ \(1.1 \, eV\)
• Germanium $\rightarrow$ \(0.7 \, eV\)
Step 2: Select correct value.
\[ \text{Band gap of silicon} = 1.1 \, eV \]
