ABSTRACT:
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.
