Multicomponent TMD Phase-field model with elastic heterogeneity

A generalized semi 2D-model for the structural transformations under mechanical strains of multi-components transition metal dichacogenide (TMD) monolayers were manipulated. In this model, not only the chemical and structural but also elastic heterogeneity, through the eigen strain method, were introduced. Basing on this model, some experimental observation can be simulated and understood better. Some qualitatively pre-results related to these phase transformations were obtained by this model, some of them are interesting and still need further study.
