Medium Why is silicon useful in semiconductor devices? AIts band gap is too large for practical carrier control at room temperature BIts conductivity can be controlled by doping and conditions CIts carrier concentration cannot be changed by temperature or illumination DIt cannot form junctions with appropriately doped regions EIt has no useful band gap for controlling charge-carrier concentration Report a problem with this question What is wrong?
