Title: Multi-principal element transition metal dichalcogenides via reactive fusion of 3D-heterostructures

Abstract

Transition metal dichalcogenides combining multiple principal elements in their structures are synthesized via mechanochemical exfoliation and spontaneous reassembly of binary precursors into 3D-heterostructures that are converted into single-phase layered materials by high-temperature reactive fusion. As a result, physical and chemical events enabling these transformations are summarized in the form of a conceivable reaction mechanism.
