The steady-state electron distribution in silicon can be approximated by a linear function of x. The maximum electron concentration occurs at x = 0 and is n(0) = 2.0 x 1016cm-3. At x = 0.012cm, the electron concentration is 5.0 x 1015cm-3. (a) Write the expression for the electron distribution in silicon for all x. (b) If the electron diffusion coefficient is Dn = 27cm2/s, determine the electron diffusion current density.
