Read the Diffusion current class notes.
In some region of a semiconductor, the hole concentration varies exponentially with distance, as shown below,
with p1 = 5.0e+12 cm-3 and L = 8 μm.
Calculate the hole diffusion current density at the point x = 0.8 μm.
The hole diffusion coefficient is Dp = 10 cm2/V·s.
