Vedclass · Answer

(D) In semiconductors,the forbidden energy gap $(E_g)$ between the valence band $(VB)$ and the conduction band $(CB)$ is small,typically on the order of $1 \ eV$ or comparable to the thermal energy $k_BT$.- Diagram $A$ shows overlapping bands,which is characteristic of a conductor.- Diagram $B$ shows a small gap,but the representation is not standard for a semiconductor.- Diagram $C$ shows a large energy gap $(E_g \gg k_BT)$,which is characteristic of an insulator.- Diagram $D$ shows a small energy gap $(E_g \approx k_BT)$,which is the characteristic energy band structure of a semiconductor.Therefore,the correct diagram is $D$.

Which of the energy band diagrams shown in the figure corresponds to that of a semiconductor?
