摘要: Here we report experimental results for a carbon nanotube (CNT) based amplitude-modulated (AM) demodulator modulation frequencies up to 100 kHz. Further, the CNT was successfully demonstrated in an actual AM radio receiver operating at carrier frequency of 1 GHz and capable demodulating high-fidelity audio. The demodulation originates from nonlinear current−voltage (IDS vs VDS) characteristic CNT, which induces rectification portion applied RF signal. By properly biasing such that point is centered on maximum I−V curve, one can maximize effect. This represents simple application nanotubes nanotechnology wireless realm.
