A potential difference is applied across (i) an issulator at 0 k (ii) a semiconductor at 0 k (iii) a metal at 0 k (iv) a reverse biased p-n junction diode at 300 k then the current passing through
Name the p-n junction diode which emit spontaneous radiation when frrward biased. How do we choose the semiconductor, to be used in those diodes, if the emitted rediation is to be in the visible region?
What is the number of junctions in a semiconductor diode ?
Which one of the following semiconductor diodes is reverse biased?
Assertion (A): Zener diode is used as a voltage regulator. Reason (R ): Zener diode operated in reverse biased condition.
Just before the reverse breakdown in a semiconductor diode -
