Van Dorp, J. Van Leeuwen, R. Venstra, W.J. Faculty Applied Sciences Department QN/Quantum Nanoscience Date 2015-09-01 Abstract We investigate the effect of mechanical strain on the dynamics of thin MoS2 nanodrum resonators. Using a piezoelectric crystal, compressive and tensile biaxial strain is induced in initially flat and buckled devices. In the flat device, we observe a remarkable strain-dependence of the resonance line width, while the change in the resonance frequency is relatively small. In the buckled device, the strain-dependence of the damping is less pronounced, and a clear hysteresis is observed. The experiment suggests that geometric imperfections, such as microscopic wrinkles, could play a role in the strong dissipation observed in nanoresonators fabricated from 2-D materials.
