主要内容:
When the characteristic length of a material shrink to 1 nm scale, many distinct physical phenomena, such as quantum confinement, enhanced many-body interactions and strong van der Waals inter-material couplings, will appear. To investigate these fascinating low-dimensional physics, we need a tool to quantitatively link the atomic structures to the physical properties of these very small nanomaterials. In this talk, I will introduce our recently developed in-situ Nano-optics + TEM, in-situ Nano-optics + CVD techniques, which combine capability of property characterization, structural characterization, and materials design/growth at individual nano-material level. Several examples of using this technique to study the 1D carbon nanotubes and 2D graphene will be demonstrated.
