||Interlayer-space engineering of van der Waals layered materials
|| Compared with their conventional 3D counterparts, matters’ properties exhibit intriguing changes when their dimension is reduced.
Among the huge varieties of low-dimension, and low-dimension-like systems, the family of transition metal dichalcogenides (TMDCs) – a kind of van der Waals (vdWs) layered materials, attract many researchers’ interest.
The members of TMDCs family share similar structures, but with a spectrum of different properties, including insulators, semiconductors, semimetals, superconductors, etc. This provides us a good platform to study the physical properties with relatively controlled and tunable parameters.
In this study, we focus on intercalating heavy transition metals into the interlayer-space of TMDCs – their vdWs gap, using the technique of molecular beam epitaxy (MBE). And to make the system thin enough to approach the 2D limitation.
