TL;DR: The controlled synthesis of ultrathin CrSe crystals, with grain size reaching the sub-millimeter scale, on mica substrates via an ambient pressure chemical vapor deposition (CVD) method is demonstrated, demonstrating obvious ferromagnetic properties at temperatures below 280 K, which has not been observed experimentally before.

Interplay between Kitaev interaction and single ion anisotropy in ferromagnetic CrI$_3$ and CrGeTe$_3$ monolayers
TL;DR: In this article, a simple Hamiltonian was developed to investigate magnetic anisotropy of CrI$_3$ and CrGeTe$3$ monolayers and the anisotropic exchange coupling in both systems was surprisingly determined to be of Kitaev-type.

Strong magnetization and Chern insulators in compressed graphene / CrI 3 van der Waals heterostructures
TL;DR: Huang et al. as mentioned in this paper showed that the van der Waals (vdW) gap can be compressed to a distance between about 3.3 and 2.4 \AA{, corresponding to a required external pressure between about 1.4 and 18.3 GPa.

Chemical synthesis of two-dimensional atomic crystals, heterostructures and superlattices
TL;DR: To explore the full potential of 2DACs requires a robust synthesis of these atomically thin materials and scalable construction of complex heterostructures with designed spatial modulation of chemical compositions and electronic structures.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
