Read the Diffusion current class notes.
In some region of a semiconductor, the electron concentration varies linearly with distance, as shown below,
with n1 = 7.0e+12 cm-3 and W = 3 μm.
Calculate the electron diffusion current density at any point 0 < x < W.
The electron diffusion coefficient is Dn = 35 cm2/V·s.
