(TU Delft Dynamics of Micro and Nano Systems) Contributor Steeneken, P.G. (promotor) Alijani, F. (promotor) Degree granting institution Delft University of Technology Date 2023-11-29 Abstract Micro and nanomechanical resonators are essential to the state-of-the-art communication, data processing, timekeeping, and sensing systems. The discovery of graphene and other two-dimensional (2D) materials has been a profound source of inspiration for the next generation of these devices, owing to their exceptional mechanical, electrical, and thermal properties. However, alongside their advantages, the atomically thin nature of these resonators also presents its own unique challenges, as the dynamic response of these resonators rapidly becomes nonlinear, where nonlinear coupling and dissipation processes manifest. To unleash the full potential of these resonators, a comprehensive understanding of the emerging nonlinear phenomena is crucial. In this pursuit, this thesis studies nonlinear dissipation pathways in 2D material resonators that arise from the coupling of their internal mechanical modes to each other as well as to theirmicroscopic physics. The thesis consists of six chapters.
