Gold, renowned for its exceptional ductility, can be delicately pounded into ethereal, gossamer-like leaves in ancient craftsmanship. This study presents an innovative solid-state uniaxial compression fabrication technique that effectively converts gold nanoparticles into two-dimensional (2D) structures through single-time quasi-static compression. The resulting morphologies of 2D gold are found to be influenced by both the initial shape of individual precursor nanoparticles and their arrangement on the substrate. To gain deeper insights into the underlying mechanisms, classical molecular dynamics simulations are employed to explore the deformation processes of gold nanoparticles. The simulations also investigate the impact of various factors such as the presence of free surfaces, particle size, orientation, and loading rate on these nanoparticles’ mechanical properties under conditions of quasi-static compression. Furthermore, the formation and structural stability of thinness 2D gold nanosheets are investigated, pushing the boundaries of thinness through the compressing process. |
