Sensitive detection of nanomechanical motion using piezoresistive signal downmixing [PDF]

Applied Physics Letters, 2005
We have developed a method of measuring rf-range resonance properties of nanoelectromechanical systems (NEMS) with integrated piezoresistive strain detectors serving as signal downmixers. The technique takes advantage of the high strain sensitivity of semiconductor-based piezoresistors, while overcoming the problem of rf signal attenuation due to a ...
