Abstract

Electric transport properties of chemically modificated carbon nanotubes (CNTs) using Si-containing organic molecules were investigated by means of the field effect transistors (FETs) technique, and presented the comparison of the FET properties between separated individual and spread-sheet samples. From the results of FET measurements for both separated individual and spread-sheet samples, it was shown that p-type semiconducting CNTs can be converted to n-type ones by exohedral silylation. It is suggested that the electron carrier are doped into CNTs from the additional silyl groups, that is, the electronic properties of CNTs can be controlled by chemically modifications of outer surface.
