Here we introduce a CO 2 -induced phase engineering strategy that achieves 2D ferromagnet via the transformation of non-van der Waals (non-vdW) VO 2 solid to 2D defective structure with identified metastable phases. Our approach requires only exposing the structure to supercritical CO 2 liquid ...
Mechanical cleavage of layered structures is the most effective method to obtain pristine two-dimensional (2D) sheet materials. However, this approach is restricted to materials in which interlayer interactions are dominated by weak van der Waals (vdW) f
In summary, our study, for the first time, achieved the atomic-precise crystal structure analysis of Cu3BHT, showcasing a unique non-van der Waals 2D structure characterized by strong interlayer interactions through Cu–S covalent bonds. Single-crystal devices of Cu3 Methods Materials CuCl2was pu...
A series of non-van der Waals 2D quaternary thiophosphates with nominal composition, Li 2 MP 2 S 6 (M = V, Mn, Fe, Co, Ni, and Zn), has been successfully synthesized through solid-state metathesis reactions by a building block approach as well as starting with a stoichiometric combinati...

generalized van der Waals theorywettingoscillatory structuresThe prediction by Cahn (1977, J. chem. Phys., 66, 3677) that a two phase fluid at a wall shows a wetting transition accompanied by a thick-thin film (prewetting) transition as the temperature increases towards the critical value ...
In contrast to the van der Waals planes the edge planes show Fermi level pinning and also an increased reactivity. The change in Fermi level position during metal deposition is different for the cleaved and cut surfaces, indicating that different mechanisms are involved. 展开 ...
Herein, a new multibit tribotronic nonvolatile memory (T-NVM) based on a graphene/hexagonal boron nitride/molybdenum disulfide van der Waals heterostructure and triboelectric nanogenerator (TENG) is proposed. The programming/erasing states can be modulated by the triboelectric potential, which is ...
