A gallium arsenide semiconductor has the following uniformly-doped, completely-ionized impurities: \( 10^{9} \) donor atoms \( / \mathrm{cm}^{3} \), and \( 10^{12} \) acceptor atoms \( / \mathrm{cm}^{3} \). Find \( \ln \left(\mathrm{p} / n_{\mathrm{i}}\right) \) at \( 500^{\circ} \mathrm{K} \).

A perfectly compensated semiconductor is one in which the donor and acceptor impurity concentrations are exactly equal. Assuming complete ionization, determine the resistivity of silicon at $T=300 \mathrm{~K}$ in which the impurity concentrations are (a) $N_{a}=N_{d}=10^{14} \mathrm{~cm}^{-3}$ (b) $N_{a}=N_{d}=10^{16} \mathrm{~cm}^{-3}$, and (c) $N_{a}=N_{d}=10^{\mathrm{ts}} \mathrm{cm}^{-3}$.
A p-type gallium arsenide semiconductor at $T=300 \mathrm{~K}$ is doped at $N_{a}=10^{16} \mathrm{~cm}^{-3}$. The excess carrier concentration varies linearly from $10^{14} \mathrm{~cm}^{-3}$ to zero over a distance of $50 \mu \mathrm{m}$. Plot the position of the quasi-Fermi levels with respect to the intrinsic Fermi level versus distance.
A new semiconductor material is to be "designed." The semiconductor is to be $\mathrm{p}$ type and doped with $5 \times 10^{15} \mathrm{~cm}^{-3}$ acceptor atoms. Assume complete ionization and assume $N_{d}=0 .$ The effective density of states functions are $N_{c}=1.2 \times 10^{19} \mathrm{~cm}^{-3}$ and $N_{\mathrm{x}}=1.8 \times 10^{19} \mathrm{~cm}^{-3}$ at $T=300 \mathrm{~K}$ and vary as $T^{2} .$ A special semiconductor device fabricated with this material requires that the hole concentration be no greater than $5.08 \times 10^{15} \mathrm{~cm}^{-3}$ at $T=350 \mathrm{~K}$. What is the minimum bandgap energy required in this new material?
