A simple method is developed to calculate Mie (Lennard‐Jones) potential parameters for metals, using crystalline state physical properties at any given temperature. Calculated values are in good agreement with some values reported in the literature.

Remarkable properties of layered metal dichalcogenides and their potential applications in various fields have raised intense interest worldwide. We report tens of microns-sized ultrathin single crystal SnS 2 flakes grown on amorphous substrates using a simple one-step thermal coevaporation process. X-ray pole figure analysis reveals that a majority of flakes are oriented with the (0001) plane parallel to the substrate and a preferred fiber texture. For few-layer-thick SnS 2 , Moire patterns of 6-fold and 12-fold symmetries are observed by transmission electron microscopy imaging and diffraction. These patterns result from the relative rotation between SnS 2 layers in the ultrathin flake. The 12-fold symmetry is consistent with a known quasicrystal pattern. The photoluminescence spectrum supports that these ultrathin flakes possess a direct bandgap. Carrier lifetime measured by time resolved photoluminescence of a single flake is a few nanoseconds. These results improve our understanding of the formation and shape of ultrathin SnS 2 flakes.

Structural stabilities of simple crystals (h.c.p., f.c.c., and b.c.c.) are investigated using both, two‐body and three‐body interactions. A parametrical analysis is performed. The results emphasized the importance of multibody forces to explain structures such as b.c.c. Furthermore, calculations predict that, in general, the stability of crystals changes as h.c.p. → f.c.c. → b.c.c. with increasing intensity of three‐body interactions. For selected cases the possibility of structural transformations (such as b.c.c. → f.c.c.) are discussed.
