Problem 6 Consider a GaAs pn junction diode at T=300 K. Determine the electric field in neutral n-region for the GaAs pn junction diode in the diode for a forward-bias voltage of $V_a$ = 1 V. We assume mobilities for GaAs are $\mu_n$ = 8500 cm$^2$/V-s and $\mu_p$ = 400 cm$^2$/V-s. $N_a$ = 8 \times 10$^{15}$ cm$^{-3}$ $N_d$ = 2 \times 10$^{16}$ cm$^{-3}$ $D_n$ = 210 cm$^2$/s $D_p$ = 8 cm$^2$/s $\tau_{n0}$ = 10$^{-7}$ s $\tau_{p0}$ = 5 \times 10$^{-8}$ s number example (V/cm) 1 7.108 \times 10$^{-1}$ 2 7.108 \times 10$^{-2}$ 3 7.108 \times 10$^{-3}$ 4 7.108 \times 10$^{-4}$ 5 7.108 \times 10$^{-5}$
