Emerging oxidized and defective phases in low-dimensional CrCl3

Abstract: Two-dimensional (2D) magnets like chromium trihalides CrX3 (X = I, Br, Cl) represent a frontier for spintronics applications and, in particular, CrCl3 has attracted research interest for its relative stability...

“…Obviously, contamination is inevitable in ambient conditions and causes effects not present in the pristine CrCl 3 . Indeed, as reported in a previous study [10], CrCl 3 few-layers result prone to oxidation manifesting an extrinsic O-CrCl 3 reconstructed structure on the surface flakes, protected by Cr 2 O 3 on the edges. This phase is particularly stable as the oxygen atoms intercalate in the hybridized CrCl 3 monolayer altering the electronic structure and inducing doping [10].…”

“…Moreover, it must be considered that the whole class of 2D vdW materials manifests vacancy defects [11][12][13], especially once exfoliated. In the case of mechanically exfoliated CrCl 3 , the flakes have intrinsically Cl vacancies with a concentration of about 2% that can be increased up to a 5% via thermal annealing [10], similarly to what is found experimentally in transition metal dichalcogenides [11,14].…”
