Physically joining p-type and n-type slabs doesn’t form a proper p-n junction because their crystal lattices remain discontinuous at the interface, causing defects. True p-n junctions are created by doping a single crystal to ensure lattice continuity, enabling the essential diffusion of charge carriers and formation of a depletion region.
The depletion region in a p-n junction is the area near the junction where free electrons and holes recombine, leaving behind fixed ions. This creates an electric field, prevents further charge carrier movement, and acts as an insulating barrier. For more visit here: https://www.tiwariacademy.com/ncRead more

An extrinsic semiconductor is a material whose electrical conductivity is enhanced by doping it with impurities. These impurities introduce free electrons (n-type) or holes (p-type), significantly increasing charge carrier concentration compared to a pure, intrinsic semiconductor. For more visit herRead more

(i) In forward bias, the depletion layer's width decreases as the applied voltage reduces the junction's potential barrier, allowing charge carriers to flow. (ii) In reverse bias, the depletion layer's width increases as the applied voltage strengthens the junction's potential barrier, preventing cuRead more

Why can’t we take one slab of p-type semiconductor and physically join it to another slab of n-type semiconductor to get p – n junction?
