Question

what is barrier voltage?​

Answer 1

Answer:

It is the minimum voltage required to start current inP-N junction of semiconductors..

Answer 2

Answer:

Barrier voltage, or barrier potential, is the minimum voltage required to start current in P-N junction of semiconductors. It is the voltage to start current through a joint of two dissimilar materials. In diodes the barrier potential varies from 0.3 V to 0.7 V depending upon the semiconductor materials.
