in a p+-n junction, the n side has a donor concentration of 10^16 cm^-3. if ni=10^10cm^-3, the relative dielectric constant εr = 12, dn=50cm^2/s, Dp = 20cm^2/s, and the electron and hole minority carriers have lifetimes τ=100ns and 50 ns, respectively, and a forward bias of .6V, calculate the hole diffusion current density 2μm fromt he depletion edge of the n side. if we double the p+ doping, what effect will it have on this hole diffusion current?
