Question

The space charge region in a p-n junction is also referred to as the concentration region due to the build-up of charges there​

Answer 1

The space charge region in a p-n junction is also referred to as the concentration region due to the build-up of charges​ is false.

Explanation

- The space charge region in a p-n junction is also referred to as the depletion region because there is a diffusion of the charges as all the free charge carriers are removed from the space.  

- The formation of depletion zone helps the p-n junction to function as a diode that is allowing current to pass in one direction.

So the space charge region is not a concentration region rather a depletion region.

Hope this helps.

Answer 2

This statement is false - the space charge region is called as the depletion region where all the free charges are removed thus creating diffusion of charges.

This further causes the p-n junction to act as a diode which allows current to flow through a single direction. This perfectly explains why charges in free region is not called as concentration region.
