APPLICATIONS OF TECHNOLOGY:
- Electronics, as a filter and an amplifier
- Wireless communications, as a low-power RF receiver and transmitter
- Optics, as a highly sensitive RF photon detector
- Fundamental scientific research, as a NEMS device
- Exhibits infinite gain at pumping voltages under 10V
- Low overhead power consumption (10 – 1,000 nW)
- Highly sensitive detector of RF radiation
A research team led by Berkeley Lab’s Alex Zettl has developed a nanoscale electro-mechanical amplifier that can be used for enhanced radio wave detection and electronic signal amplification.
Operating this carbon nanotube-based NEMS parametric amplifier in the limit of strong coupling between mechanical vibrations and field emission tunneling current yields a phase-sensitive, variable gain, band-pass-filtering amplifier for electronic signal processing. At the same time, it can operate as a variable-sensitivity, tunable detector and transducer of RF electromagnetic waves.
