The frequency of a musical instrument, such as a guitar string, is tunable over more than one octave, i.e. a ratio of two between the maximum and minimum frequency. It is defined as f=(k/m)^0.5 where k is the spring constant and m the mass of the resonator. To be successfully integrated into devices or sensors, the resonator frequency must be tuned. When the dimensions are reduced to nanometer sizes, such precise tuning is difficult to achieve in-situ. There is therefore a demand for simple and robust techniques to tune mechanical resonances at the nanoscale, and for nanoresonators that can be tuned over a wide frequency window. Among different nanoresonators, carbon nanotubes and two-dimensional (2D) materials have shown the best performance for mechanical frequency tuning, Here we design a thermally tuned nanomechanical resonator, using Joule heating and a very low electrical voltage, which lies at the interface between thermal transport in 2D materials and nanomechanics, with a focus on electrothermal actuation of mechanical vibrations and their frequency tuning.

(a) Schematic of the suspended MoS₂ membrane in a back-gated transistor configuration, laterally contacted by two gold electrodes (b) Optical microscopy image of the sample. The scale bar is 2µm (c) Mechanical response of the membrane near 35.6 MHz, as measured by our optical technique. (a) Variation of the frequency as a function of the heating voltage Vds. It shows a huge tunability of the frequency from 34 to 10 MHz. (b) Efficiency and amplitude values of our frequency variation for our work and other references on TMDs and 2D heterostructures.
