Research Abstract

A carbon-nanotube field-effect transistor (CNT-FET) generally shows p-type conduction, however, it can be converted to ambipolar or unipolar n-type behavior by polymer coating even under an ambient condition. In this study, carrier-type conversion of CNT-FETs using a water-soluble poly-vinyl alcohol (PVA) was demonstrated. Based on the capacitance-voltage characteristics, it is found that the PVA film has positive charges in high density. The conversion is possibly due to the existence of the induced charges, which was formed at the CNT/PVA interfaces by the polymer coating.
