Question

5. p-n junctions are typically not made by physical pressing p and n doped materials that were independently synthesized as two separate pieces.

 A.True 

B. False

Answer 1

The answer is true- p-n junctions are typically not made by physical pressing p and n doped materials that were independently synthesized as two separate pieces.

If two such independent pieces were to be placed next to each other, a p-n junction wouldn't be formed. The actual process entails using a single crystal of semiconductor material with one end being doped p-type and the other, n-type. The result is the formation of a potential barrier at the junction.
