Question

what type of semiconductor obtained when si or he are doped with element of group 13 such as b or al and why​

Answer 1

By doping pure silicon with Group V elements such as phosphorus, extra valence electrons are added that become unbonded from individual atoms and allow the compound to be an electrically conductive n-type semiconductor.

Answer 2

Answer:

. The n- type semiconductors are obtained when Si or Ge are doped with elements of group 15, eg, Arenic (As), while p-type semiconductors are obtained when Si or GGe are doped with traces of elements of group 13
