| Abstract Scope |
Low-dimensional 0D metallic nanoparticles are intrinsically faceted with geometric shapes, exhibiting high structural symmetry due to net surface energy minimization during synthesis. Solution-based, seed-mediated colloidal synthesis have been the prevailing strategies for synthesizing asymmetry nanoparticles and achieving control of nanoparticle morphological anisotropy. In contrast, morphological control via top-down strategies has remained under-explored. In this report, a novel, solid-state, uniaxial compression fabrication technique is demonstrated, enabling deterministic control over nanoparticle morphological anisotropy. This generalizable technique facilitates the transformation of 0D (Au) nanoparticles into anisotropic two-dimensional (2D) morphologies. The post-compression morphology of 2D Au exhibits dependence on the individual precursor 0D nanoparticle morphology, dimensions (0D nanosphere diameter), and on-substrate arrangement (e.g., interparticle separation, packing order). Overall, this versatile and generalizable solid-state transformation technique enables new pathways to investigate the mechanics of anisotropic morphological transformation of arbitrary metallic nanoparticles and their emergent phenomena. |
