Notes:
We show that the intercalating of alkali atoms with adequate concentration can transform ametallic single-walled carbon nanotube (SWCNT) into a semiconductor tube or a semiconductorSWCNT into a semiconductor tube with different band gaps due to a unique feature of the bandstructures in SWCNTs. Results of Li2C60 in the (5,0) tube, Li2C112 in the (4,2) tube and K2C112 in the(7,0) tube show that this transition mechanism is quite general
