Making topological materials into nanoscale systems can enhance the properties of the topological surface states for fundamental studies and potential applications.  In this talk, I will discuss our efforts on synthesis of topological nanomaterials, such as nanowires of SnTe (topological crystalline insulator), superconducting In-doped SnTe (candidate topological superconductor), and MoP (triple point topological metal), and thickness-controlled thin films of MoTe2 (quantum spin Hall state in monolayer).   Growth dynamics of nanomaterial synthesis and several synthesis improvements will be presented to showcase the challenges and opportunities in synthesis of topological nanomaterials.  Transport properties of SnTe and MoP nanowires will be presented.  Lastly, in situ cryo-TEM studies of size-dependent phase transitions in SnTe nanowires and MoTe2 flakes will be presented to show the advantages of topological nanomaterials for studying phase transitions in real space.
