- 0.72 eV
- 1.1 eV
- 0.5 eV
- 1.5 eV
- 0.65 eV
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The band gap energy of Germanium is 0.72 eV. This means that an electron requires 0.72 eV of energy to transition from the valence band to the conduction band, allowing electrical conduction.
