which type of semiconductor is formed when (i) Germanium is doped with Indium? (ii). Silicon is doped with Bismuth?

i) Germanium belongs  to group 14 whereas Indium belongs to 13th group. Hence, they together form a p-type semiconductor.
ii) Silicon is a group 14 element whereas Bismuth belongs to 15th group. Hence, they together form a n-type semiconductor.
