Question

Does the conductance of a semiconducter change when the Fermi level $E_F$ stays the same, but the distance to the valence band $E_V$ increases?

Answer 1

When talking about n-type semiconductors and assuming roomtemperature: Does only the Fermi level determine the conductance of the semiconductor or also the energy difference between the Fermi level and the valence band? So, is there a difference in conductance, when you compare situation (a) to situation (b)?

Answer 2

Hola mate !! ✨✨

here's your answer....⬇️⬇️

▶️yes the conductance of a semiconductor will change . the conductivity of a semiconductor depends on the electrons crossing the valence band to reach conduction band .

▶️but , if the distance to the valence band is increased more energy will be required by the electrons to cross the forbidden zone . but if the energy is not provided then the conductivity will decrease.

hope it helps !! ❤️❤️
