Title: CARBON NANOTUBES FOR WIRELESS COMMUNICATION AND RADIO TRANSMISSION

Abstract:
Described herein are systems and methods in which a carbon nanotube (CNT) is used as a demodulator of amplitude-modulated (AM) signals. Due to the nonlinear current-voltage (I-V) characteristics of a CNT, the CNT induces rectification of an applied RF signal enabling the CNT to function as a demodulator of an amplitude-modulated (AM) RF signal. By properly biasing the CNT such that the operating point is centered on the maximum portion of the I-V curve, the demodulation effect of the CNT can be maximized. The present invention is useful for possible nanoscale wireless communications systems, e.g., nanoscale radios.
