This WOCSDICE 2010 paper by Sikula, Handel, and Truong examines fundamental noise in resonant ZnO sensors. The research investigates quantum 1/f noise and other fundamental noise sources in zinc oxide based resonant sensors including bulk acoustic wave resonators, surface acoustic wave devices, and nanowire resonators used for mass detection and chemical sensing, analyzing how material properties, crystal quality, and piezoelectric coupling affect noise performance and ultimate detection sensitivity for biosensing and gas detection applications.
