Question

The ______, a property of materials C, Si, and Ge depends upon the energy gap between their conduction and valence bands.

Answer 1

The conductivity, a property of materials C, Si, and Ge depends upon the energy gap between their conduction and valence bands.

Explanation:

The conductivity of materials like Carbon (C), Silicon (Si), and Germanium (Ge) depends on the energy gap between the valence band and conduction band. A smaller energy gap allows electrons to move easily to the conduction band, increasing conductivity. A larger energy gap results in lower conductivity.
