$5.$ Cuprous oxide $\backslash (\backslash$mathrm$\{$Cu$\}\_\{2\}\backslash$mathrm$\{$O$\}\backslash )$ can be used as semiconductor. Metal oxides in general are known for their self$-$doping that makes them intrinsically $\backslash ($ n $\backslash )-$or p$-$type even in the absence of extrinsic impurities. Below you can see diagrams with the formation energies of intrinsic point defects in this material and localized energy levels associated with them. Guess the conductivity type of intrinsic $\backslash (\backslash$mathrm$\{$Cu$\}\_\{2\}\backslash$mathrm$\{$O$\}\backslash ).$ Comment on the specifics of self$-$doping process. $(3$ points$)$
