The electron concentration in a sample of n-type silicon varies linearly from 1017 cm-3 at x = 0 to 6 × 1016 cm-3 at x = 4 μm. There is no applied electric field. The electron current density is experimentally measured to be - 400 A/cm2. What is the electron diffusion coefficient (in cm2/s)?
Enter numerical value using the virtual keypad. Round off where necessary.
