Although, from a kinetic perspective, both the size and morphology of the nanocrystals can be precisely controlled using an optimal and suitable combination of various solvents and stabilizers. The process, by which nanocrystals mutually interact with each other to generate larger structures via particle-particle or particle-solvent interactions is referred to as nanocrystal-based self-assembly. Recent research also suggests the oriented attachment (OA) of monomers mechanism could be a plausible fundamental process that helps to explain the initial growth process after nucleation events that occur when there is a significant concentration of both monomers and clusters . Another outstanding crystal growth process is the OA mechanism, which involves the spontaneous self-organization and coalescence of adjacent particles by eliminating a common boundary that shares a standard crystallographic orientation with a flat interface (see Figure and)) . Hence, the driving force that induces the growth mechanism of OA is not specific, but likely due to a decrease in the free energies of the surface and grain boundaries . However, it is known that the reduction in surface energy eliminates some crystalline facets of high energy. In this way, nanocrystals collide and form loosely bound compounds, which can reorganize and form irreversible attachments along preferred crystallographic orientations .
