DOI: 10.1002/adfm.202313067
Abstract: Benefited from the lower dimensionality compared to their 3D counterpart, 2D flat‐band systems provide cleaner lattice models, easier experimental verification, and higher tunability, which make the 2D van der Waals (vdW) system an ideal playground… read more here.

DOI: 10.1002/adma.202300572
Abstract: After the preparation of two-dimensional (2D) electronic flat band (EFB) in van der Waals (vdW) superlattices, recent measurements suggested the existence of one-dimensional (1D) electronic flat bands (1D-EFBs) in twisted vdW bilayers. However, realisation of… read more here.
