Nanoscience today enables exciting emergences of low-dimensional nanostructures and new materials with previously inaccessible properties. We explore these properties, coupled with mechanical degrees of freedom in designed nanostructures, to engineer new nanomachines and transducers, for sensing and information processing. In particular, nanoscale electromechanical systems (NEMS) operating in their multiple resonant modes can make a exquisite platform. In this talk, I will focus on introducing 2D NEMS based on atomically-thin crystals. While graphene has been very well known as the hallmark of 2D crystals, other interesting 2D crystals with tunable bandgaps have emerged, such as layers from transition metal di-chalcogenides (TMDCs) and black phosphorus. Atomically-thin structures derived from these materials possess a number of interesting electrical, optical, and mechanical properties, and are attractive for new nanodevices. I will describe our recent experiments on demonstrating various high-frequency MoS2 and other 2D NEMS resonators. By performing sensitive optical and electronic measurements, in combination with modeling, we quantify the performance of these 2D NEMS, and evaluate their potential applications and fundamental limits. Challenges and advances in experimental techniques will also be discussed.
