Question

How does the interface between physically joined p-type and n-type slabs act on charge carriers?

पर्याय

• It eliminates the barrier potential in reverse bias

• It makes diffusion and drift currents equal in forward bias

• It acts as a discontinuity (barrier) to charge carriers

• It acts as a continuous crystal lattice for charge carriers

Answer 1

The lack of continuous atomic contact makes the interface a discontinuity, or barrier, to charge carriers. As a result, physically joining the slabs does not produce a true p-n junction.
