Hi

I was wondering why they only use 5th and 3rd groups elements to create n-type and p-type semiconductors respectively. Couldn't we mix 6th or 2nd groups' elements instead to make the semiconductors? What would happen if we do this? Perhaps elements of those groups will bind to the silicon or germanium atoms too strongly. Please guide me. Thanks.

Cheers

Perhaps what you suggest, has been tried by people who produce semiconductors, proved not to work, and therefore is not done ??
