p-n junction is a semiconductor diode. It is obtained by bringing p-type semiconductor inclose contact with n-type semiconductor. A thin layer is developed at the p-n junction which is devoid of any charge carrier but has immobile ions. It is called depletion layer. At the junction a potential barrier appears, which does not allow the movement of majority charge carriers across the junction in the absence of any biasing of the junction. p-n junction offer low resistance when forward biased and high resistance when reverse biased. Read the above paragaph and answer the following question: (i) Can we measure the potential barrier of p-n junction by putting a sensitive voltmeter across its terminals? (ii) What practical lesson do you draw from the above study?

Q6.When "p" - "n" junction diode is forward biased,then (a)the depletion region is reduced and barrier height is increased (b) the depletion region is widened and barrier height is reduced (c)both the depletion region and barrier height are reduced (d) both the depletion region and barrier height are increased

Explain with the help of a diagram, how depletion region and potential barrier are formed in a junction diode. If a small voltage is applied to a p-n junction diode how will the barrier potential be affected when it is (i) forward biased and (ii) reverse biased?
