The average gap for Germanium at OK is:
Correct answer: C. 6.72 ev
- A. 1.12 ev
- B. 0.02 ev
- C. 6.72 ev
- D. 7.2 ev
Explanation
The correct answer is c) 6.72 eV because it accurately represents the bandgap energy of germanium. The bandgap energy is a critical parameter in semiconductors, representing the energy difference between the valence band and the conduction band. In the case of germanium, the bandgap energy is approximately 0.72 eV. This value is important for understanding the electronic properties of germanium-based devices, such as transistors and diodes, as it dictates their conductivity and optical properties.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
