abstract

In this thesis, the one-pot, colloidal solution-liquid-solid (SLS) synthesis procedure for antimony telluride (Sb2Te3) spiral-type nanoplates (STNPs), first put forward by Dun et al., is adapted to create several distinct nanostructures. In particular, Sb2Te3 moiré superlattices (MSLs) are synthesized with observed twist angles up to 0.52°. Emphasis is given to modifications of the typical reaction procedure that lead to visible and controllable changes in the resulting nanostructures, observed primarily using Transmission Electron Microscopy (TEM). Small-angle MSLs of other van der Waals (vdW) materials have been found to host several emergent quantum phenomena associated with high electron correlations, and while the study of MSLs has surged in recent years, the difficulty of fabricating these structures remains high. The relatively simple synthesis methods put forward in this thesis hope to facilitate future investigation into the electronic properties of Sb2Te3 MSLs.
