3- In GaAs, Na (x) = Na exp(-v/L) for 0 S5L, where L-0.1 um. and Na = 5 x10 cm Assume p, = 6000 cmV-s and T=300 K. (a) Derive the expression for the electron diffusion current density versus distance over the given range of x. (b) Determine the induced electric field that generates a drift current density that compensates the diffusion current density
