ABSTRACT:
We have constructed a fully functional, fully integrated radio receiver from a single carbon nanotube. The nanotube serves simultaneously as all essential components of a radio: antenna, tunable band-pass filter, amplifier, and demodulator. A d.c. voltage source, as supplied by a battery, powers the radio. Using carrier waves in the com. relevant 40-400 MHz range and both frequency and amplitude modulation techniques, we demonstrate successful music and voice reception.
