Question

Gold in Si introduces an acceptor level 0.54eV below and a donor level 0.35eV above . What will be the charge state of the gold levels in Si doped with (a) a high concentration of P w.r.t. gold (b) a high concentration of B w.r.t. gold? What is the effect of gold on 0 and 0 for the above two cases? Now determine the charge state of the gold levels and position of if only the gold impurity is present. Is the material n or p type?​
