Unveiling the structure and interactions of silicene grown on MoS₂: insights from hybrid molecular dynamics simulations. [PDF]

Acta Crystallogr B Struct Sci Cryst Eng Mater
The stable epitaxial growth of silicene on MoS2 requires both van der Waals and covalent interactions – without them, the silicene collapses into a disordered state. These findings offer important insights into designing stable silicene/MoS2 heterostructures for future nanotechnology applications.The interaction of silicene with MoS2 surfaces has an ...
