This ISSSR 2010 paper by Handel, Truong, and Nasiri Avanaki examines quantum 1/f piezoelectric transducer size fluctuations. The research investigates fundamental quantum mechanical fluctuations in the physical dimensions and vibrational modes of piezoelectric resonators, showing that these size fluctuations produce 1/f frequency noise that limits stability in quartz crystal oscillators, MEMS timing devices, and resonant sensors, providing insights for designing ultra-stable frequency references and precision sensors.
