Hi everyone,
I need to know "why only group 3 and 5 elements are used to dope with silicon and why not group 2 and 6 elements. from basic device physics we know that group 3 elements will have 3 outermost electrons which will creates a hole on doping with silicon(4 outermost electrons). similarly group 5 element will give an electron.
My question is, instead of group 3 and 5, can't we use group 2 and 6 elements with silicon so that will get two holes and two electrons respectively which will be an advantage. correct me if I am wrong.

Can anyone please answer for the above question and can please share any materials if they have regarding the same. thanks in advance. :)
