FET properties of chemically modified carbon nanotubes Original Research Article

Electric 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 measurement for both samples, it was shown that p-type CNTs–FETs can be converted to n-type ones by exohedral silylation. This results show that the characteristics of the CNTs–FET can be controlled by chemically modifications of outer surface of CNTs.
