Consider the two-dimensional representation of the semiconductor GaAs shown below: If Si atoms are inserted as dopants and exclusively replace Ga atoms in the lattice, will the Si-doped GaAs material be n-type or p-type? Explain. What if the Si atoms exclusively replace As atoms? Explain.

With appropriate illustration/equation (if any), give your comments on the truthfulness of the following statements: (a) The volatility of gallium hinders growing bulk GaAs using the Czochralski method. (b) Ionized acceptor atoms create holes in the conduction band. (c) Increasing the dopant concentration will increase the separation between the Fermi level and the intrinsic level. (d) The color of radiated photons can be varied by adding impurities into a semiconductor.
