Vedclass · Answer

(C) The contact potential (or barrier potential) $V_B$ of a $P-N$ junction is an intrinsic property determined by the doping concentration and the material properties of the semiconductor.When an external forward bias is applied to the $P-N$ junction,the effective barrier potential decreases,allowing current to flow.However,the contact potential itself is a fixed characteristic of the junction at a given temperature.Even when the current increases due to an increase in the applied forward bias,the contact potential (the potential barrier height) remains unchanged as a physical property of the junction structure itself,although the effective barrier height is modified by the external voltage.

In a $P-N$ junction,when the current value increases,the contact potential ..........
