Can we measure the potential differnece across an unbiased p-n junction by connecting a sensitive voltmeter across its terminals?

Explain

Expert Answer:

No. Potential difference across p-n junction is not electro-motive force. Potential difference occurs only when it is forward biased.
 
Under biased condition there is a movement of charge carriers.
 
Due to this movment of charge carrieres we observe there is a potential difference occurs across p-n junction
