Problem- Silicon and germanium are both semiconducting elements from Group 14 in the periodic table, and both can be doped to improve their conductivity.
Predict whether each of the following would form an n-type or p-type semiconductor. (Choose either N or P from the drop down menu for each one.)
Si doped with In
Ge doped with P
Ge doped with As
Ge doped with B
