hydrazine, polyaniline, and aminobutyl phosphonic acid and carbon nanotube field effect
transistors (CNTFETs). We successfully converted p-type CNTFETs to n-type and drastically
improved the device performance in both the ON-and OFF-transistor states, utilizing
hydrazine as dopant. We effectively switched the transistor polarity between p-and n-type by
accessing different oxidation states of polyaniline. We also demonstrated the flexibility of …
