Question
Compound semiconductors can be doped to make n-type and
p-type materials, but the scientist has to make sure that the
proper atoms are substituted. For example, if Ge were doped
into GaAs, Ge could substitute for Ga, making an n-type semiconductor;
but if Ge substituted for As, the material would be
p-type. Suggest a way to dope CdSe to create a p-type material
Expert Solution
Step 1
We know that Cd has two valence electron and Se has six valence electron making total 8 valence electron. To making n-typing we have to make total valance electron more than 8 and to make p-type we have to make total valence electron less than 8.
