The p type semiconductor is
WebbA semiconductor sphere is doped with a constant charge density of p -type ρp in the central region (r < c) and n -type ρn in the outer region (r > c). The cross-sectional region of the pn junction (a < r < d) is depleted of carriers. (The total charge in this region is zero). The vacuum's permittivity is ε0 and the relative permittivity of ... WebbThe P or As are the “donors” in the “semiconductors.” The act of putting a small amount of donor into an otherwise intrinsic semiconductor is called “doping.” It is often done by heating the pure Si in contact with some donor material to about 1,000°C, in which case the donor diffuses into the main crystal.
