Abstract
Carbon nanotube field effect transistor has attracted much attention recently and is a promising candidate for next generation nanoelectronics. Here, we report our study on a transistor using single wall carbon nanotube network as the channel and a ferroelectric film as the gate dielectric. The spontaneous polarization of ferroelectric materials offers nonvolatility and controllability of the surface charges. Modulation of > 102 in the channel conductivity has been observed in the network-based transistor. Voltage pulses are used to control the transistor states; no continuous gate bias is needed. Furthermore, n -type behavior of the network channel is observed, which is attributed to a change in the Schottky barrier at the carbon nanotube-metal interface.
