Abstract :
We report experimental investigation of resonant responses of molybdenum disulfide (MoS2) nanomechanical resonators at different temperatures. We observe strong temperature hysteresis in measurements. By examining devices with different geometries under different air pressures, we determine that surface adsorption plays an important role in the observed temperature hysteresis. This opens new possibilities for studying surface processes using 2D nanomechanical resonators.
