Problem 2- A sample of silicon is doped uniformly with two different dopants: Donor density of \( 4 \times 10^{16} \mathrm{~cm}^{-3} \), and Acceptor density of \( 5 \times 10^{16} \mathrm{~cm}^{-3} \). a) Calculate electron and hole concentrations in the sample at room temperature. b) Calculate mobility of majority carrier in the sample at room temperature.
