Large tunability of strain in WO3 single-crystal microresonators controlled by exposure to H2 gas
Nicola Manca, Giordano Mattoni, Marco Pelassa +3
Strain engineering is one of the most effective approaches to manipulate the physical state of materials, control their electronic properties, and enable crucial functionalities. B…
Selective high frequency mechanical actuation driven by the VO2 electronic instability
Nicola Manca, Luca Pellegrino, Teruo Kanki +6
Micro- and nano-electromechanical resonators are a fundamental building block of modern technology, used in environmental monitoring, robotics, medical tools as well as fundamental…
Direct and parametric synchronization of a graphene self-oscillator
S. Houri, S. J. Cartamil-Bueno, M. Poot +3
We explore the dynamics of a graphene nanomechanical oscillator coupled to a reference oscillator. Circular graphene drums are forced into self-oscillation, at a frequency fosc, by…
Visualizing the motion of graphene nanodrums
Dejan Davidovikj, Jesse J. Slim, Santiago J. Cartamil - Bueno +3
Membranes of suspended two-dimensional materials show a large variability in mechanical properties, in part due to static and dynamic wrinkles. As a consequence, experiments typica…
Dynamic relaxation oscillations in a nonlinearly driven quartz crystal
S. Houri, M. J. Geuze, W. J. Venstra
We demonstrate thermo-mechanical relaxation oscillations in a strongly driven quartz crystal. Dynamic bifurcation leads to two stable oscillation states with a distinct electrical…
Strain-dependent damping in nanomechanical resonators from thin crystals
E. Kramer, D. J. J. van Dorp, R. van Leeuwen +1
We investigate the effect of mechanical strain on the dynamics of thin nanodrum resonators. Using a piezoelectric crystal, compressive and tensile biaxial strain i…
