Vedclass · Answer

(A) $Ge$ is a group $14$ element. $As, P, Sb,$ and $Bi$ are group $15$ elements. When a group $14$ element is doped with a group $15$ element,there is an extra electron available after forming four covalent bonds with the neighboring $Ge$ atoms. This excess electron increases the conductivity of the semiconductor,resulting in an $n-$ type semiconductor.

What type of semiconductor is obtained by doping $Ge$ with $As$ $(P, Sb, Bi)$?
