It is deemed unprofessional to give your notice over email. As Uhhrrr said, do it over the phone (since meeting your boss is not possible) as a matter of courtesy.
Also, you seem pretty sure about wanting to quit. In case you are not sure, a simple discussion/negotiation with your boss might be better than to just give your notice.
