No

Vedclass · Answer

(B) No,because in this case,no current passes through the voltmeter and hence no deflection is obtained in it.Reason: The barrier potential is the potential difference across the depletion layer. Since there are no free charge carriers in the depletion layer,connecting a voltmeter across these boundaries does not allow any current to flow through the device. Therefore,the voltmeter cannot measure the potential barrier.

Can the potential barrier across a $p-n$ junction be measured by simply connecting a voltmeter across the junction?
