Hi everyone.
i have a question about formation of p-type and n-type semiconductor.
1)why we use trivalent impurity in order to form p-type semiconductor??? we can use divalent impurity, due to which there form two holes and semiconductor will conduct more.
2)why we use pentavalent impurity in order to fom n-type semicnoductor???? we can use hexavalent, due to which there form two free electrons and semiconductor will conduct more.
