Vedclass · Answer

(A) At room temperature,some electrons in the valence band gain sufficient thermal energy to jump into the conduction band. As a result,the valence band becomes partially empty and the conduction band becomes partially filled. At $0 \ K$ temperature,the valence band is completely filled and the conduction band is completely empty in a semiconductor.
