The wafers are often flippantly p-variety-doped. A surface area diffusion of n-kind dopants is carried out around the entrance side in the wafer. This forms a p–n junction a few hundred nanometers underneath the surface. They encompass modest crystals giving the fabric its standard metal flake result.
