Suppose the hole concentration in silicon sample is described mathematically by p(x) = 10^5 + 10^19 exp(-x/Lp) holes/cm3 , x ≥ 0 in which L p is known as the diffusion length for holes and is equal to 2.0 µm. Find the diffusion current density for holes as a function of distance for x ≥ 0 if Dp = 15 cm2/s. What is the diffusion current at x = 0 if the cross-sectional area is 10 µm^2?
