Consider a Si semiconductor at room temperature having electron concentration increased linearly from 5 x 107

Consider a Si semiconductor at room temperature having electron concentration increased linearly from 5 x 107 cm-3 at x = 1um until x = 5um. Given the electron diffusion current density, Jn(diff) is 9A/cm and electron diffusion coefficient, Dn = 20cm/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).
