Question

Can we take one slab of p - type semiconductor and physically join it to another n - type semiconductor to get p - n junction?

Answer 1

Answer:No

Explanation:

Answer 2

The theory of joining the p type semiconductor and n semiconductor is not valid.

• The important thing is the depletion layer between the p-n junction.
• This layer cannot be made when we attach the both as same.
• The actual diagram is not same as given in books of p-n junction.
• The properties of temperature and others will effect the junction if they join separately .
• There is proper doping on the semiconductor to form the semiconductor.
• That's why it is not possible.
