\[conduction band width band gap \(\longrightarrow \mathrm{E}_{\mathrm{g}} \uparrow\) valence band width\]
- All \(E_{[1}, E_{q,}, E_{v}\)increases
- \(\mathrm{E}_{\mathbf{I}}\) and \(E_{\mathbf{v}}\) increases but \(\mathrm{E}_{\mathrm{b}}\) decreases
- \(\mathrm{E}_{\mathbf{I}}\) and \(E_{\mathbf{v}}\) decreases but \(\mathrm{E}_{\mathrm{b}}\) increases
- All \(E_{[1}, E_{q,}, E_{v}\)decreases
Answer
(B) E _ I and E_ v increases but E _ b decreases
