An n-type semiconductor is created when pure semiconductors, like Si and Ge, are doped with pentavalent elements. As can be seen in the image above, when a pentavalent atom takes the place of a Si atom, four of its electrons bond with four neighbouring Si atoms. However, the fifth electron remains loosely bound to the parent atom. Hence, the ...
