Question

what is junction barrier​

Answer 1

Eventually a state of equilibrium (electrically neutral situation) will occur producing a “potential barrier” zone around the area of the junction as the donor atoms repel the holes and the acceptor atoms repel the electrons. ... This area around the PN Junction is now called the Depletion Layer.
