Consider a Si semiconductor at room temperature having electron concentration increased linearly from 5 x 10¹7 cm-3 at x = 1um until x = 5um. Given the electron diffusion current density, Jn(diff) is 9A/cm² and electron diffusion coefficient, Dn = 20cm²/s. i) ii) iii) Sketch the electron concentration graph versus length, x Calculate the electron concentration at x = 5um. Illustrate the direction of electron diffusion and electron diffusion current density, In(diff).
