“…where N is the number of degrees-of-freedom, and the coefficients α (i) jk and γ (i) jkl are the quadratic and cubic coupling terms that depend on the geometry, elasticity, and curvature of the membrane, but can also originate from e.g. electrostatic or optical forces, resulting in mode coupling between 2D materials and SiN membranes [158] or cavity modes [29], as will be discussed later. Besides the nonlinear stiffness mode coupling terms in equation ( 23), there is a similar set of nonlinear damping mode coupling terms like…”

The dynamics of suspended two-dimensional (2D) materials has received increasing attention during the last decade, yielding new techniques to study and interpret the physics that governs the motion of atomically thin layers. This has led to insights into the role of thermodynamic and nonlinear effects as well as the mechanisms that govern dissipation and stiffness in these resonators. In this review, we present the current state-of-the-art in the experimental study of the dynamics of 2D membranes. The focus will be both on the experimental measurement techniques and on the interpretation of the physical phenomena exhibited by atomically thin membranes in the linear and nonlinear regimes. We will show that resonant 2D membranes have emerged both as sensitive probes of condensed matter physics in ultrathin layers, and as sensitive elements to monitor small external forces or other changes in the environment. New directions for utilizing suspended 2D membranes for material characterization, thermal transport, and gas interactions will be discussed and we conclude by outlining the challenges and opportunities in this upcoming field.

“…To examine whether alternative materials could allow for better performing resonators in the future, we consider silicon carbide, [ 48,120,121 ] graphene, [ 15,104,122 ] and diamond, [ 123–125 ] comparing their upper‐bounds of performance relative to silicon nitride. The upper‐bounds are calculated by assuming the material's intrinsic quality factor is the highest experimentally demonstrated to our knowledge at room temperature, [ 121,123,126 ] and their dissipation dilution limit is set by the material yield stress, [ 48,117,127 ] as described in ref.…”

Nanomechanical resonators have applications in a wide variety of technologies ranging from biochemical sensors to mobile communications, quantum computing, inertial sensing, and precision navigation. The quality factor of the mechanical resonance is critical for many applications. Until recently, mechanical quality factors rarely exceeded a million. In the past few years however, new methods have been developed to exceed this boundary. These methods involve careful engineering of the structure of the nanomechanical resonator, including the use of acoustic bandgaps and nested structures to suppress dissipation into the substrate, and the use of dissipation dilution and strain engineering to increase the mechanical frequency and suppress intrinsic dissipation. Together, they have allowed quality factors to reach values near a billion at room temperature, resulting in exceptionally low dissipation. This review aims to provide a pedagogical introduction to these new methods, primarily targeted to readers who are new to the field, together with an overview of the existing state‐of‐the‐art, what may be possible in the future, and a perspective on the future applications of these extreme‐high quality resonators.
