12. (20 points + 2 bonus points) A silicon sample is uniformly doped with $2 \times 10^{17} \text{cm}^{-3}$ acceptor atoms at $T = 300$ Kelvin and has the following properties: $D_n = 16.8 \text{cm}^2/\text{s}$, $D_p = 6.5 \text{cm}^2/\text{s}$, $\tau_{n0} = 6 \times 10^{-6} \text{s}$, and $\tau_{p0} = 2 \times 10^{-6} \text{s}$. An external light source was turned on at time $t = 0$ producing a uniform concentration of excess carriers at a generation rate of $g' = 3 \times 10^{21} \text{cm}^{-3} \text{s}^{-1}$. This external light source was turned off at $t = 4 \times 10^{-6} \text{s}$. (a). Find the excess carrier concentration at $t = 4 \times 10^{-6} \text{s}$; (b). Find the conductivity of this sample at $t = 4 \times 10^{-6} \text{s}$; (c). Derive the expression for the excess carrier concentration at $t \ge 4 \times 10^{-6} \text{s}$; (d). Derive the expression for the sample's conductivity as a function of time at $t \ge 4 \times 10^{-6} \text{s}$.
