All of the above.

Vedclass · Answer

(D) The correct answer is $D$. $1$. At $0 \ K$,an insulator has no free charge carriers,so the current is zero. $2$. At $0 \ K$,a semiconductor behaves as a perfect insulator because all valence electrons are bound,so the current is zero. $3$. In a $P-N$ junction diode at $300 \ K$,when reverse biased,a small finite current (reverse saturation current) flows due to the presence of minority charge carriers. Since all these statements are correct,the answer is $D$.

When a potential difference is applied across,the current passing through:
