Journal ArticleDOI
Multifunctional nanomechanical systems via tunably coupled piezoelectric actuation.
Sotiris C. Masmanidis,R. B. Karabalin,Iwijn De Vlaminck,Gustaaf Borghs,Mark R. Freeman,Michael L. Roukes +5 more
TL;DR: This work employed epitaxial piezoelectric semiconductors to obtain efficient and fully integrated NEMS actuation, which is based on exploitation of the interaction between piezOElectric strain and built-in charge depletion.
Journal ArticleDOI
Phase Synchronization of Two Anharmonic Nanomechanical Oscillators
Matthew H. Matheny,Matt Grau,Luis Guillermo Villanueva,R. B. Karabalin,Michael Cross,Michael L. Roukes +5 more
TL;DR: This work establishes that oscillator networks constructed from nanomechanical resonators form an ideal laboratory to study synchronization--given their high-quality factors, small footprint, and ease of cointegration with modern electronic signal processing technologies.
Journal ArticleDOI
Nonlinear dynamics and chaos in two coupled nanomechanical resonators
TL;DR: In this article, two elastically coupled nanomechanical resonators driven independently near their resonance frequencies show intricate nonlinear dynamics, including period doubling transitions and chaos, for large vibration amplitudes.
Journal ArticleDOI
Piezoelectric nanoelectromechanical resonators based on aluminum nitride thin films
R. B. Karabalin,Matthew H. Matheny,X. L. Feng,Emmanuel Defay,G. Le Rhun,C. Marcoux,Sebastien Hentz,P. Andreucci,Michael L. Roukes +8 more
TL;DR: In this article, the authors demonstrate piezoelectrically actuated, electrically tunable nanomechanical resonators based on multilayers containing a 100-nm-thin aluminum nitride (AlN) layer.
Journal ArticleDOI
Surpassing Fundamental Limits of Oscillators Using Nonlinear Resonators
Luis Guillermo Villanueva,Eyal Kenig,R. B. Karabalin,Matthew H. Matheny,Ron Lifshitz,Michael Cross,Michael L. Roukes +6 more
TL;DR: It is shown that by operating the oscillator at special points in the resonator's anharmonic regime the authors can overcome fundamental limitations of oscillator performance due to thermodynamic noise as well as practical limitations due to noise from the sustaining circuit.
