The forbidden energy gap of carbon in diamond structure is ______?

Review the verified answer and explanation for this SPSC – Sindh Public Service Commission past-paper question on CampusFin.

The forbidden energy gap of carbon in diamond structure is ______? Answer: 5.5eV

The forbidden energy gap of carbon in the diamond structure is approximately 5.5 eV (electron volts), a value that classifies diamond as a strong electrical insulator with a wide band gap. This large gap means a significant amount of energy is required for electrons to jump from the filled valence band to the empty conduction band, hindering electrical conductivity at room temperature.
