However, maintaining ferroelectricity has been hampered by intrinsic depolarization effects. Here, by combining first-principles calculations and experimental studies, we report on the discovery of robust room-temperature out-of-plane ferroelectricity which is realized in the thinnest monolayer MoTe 2 with unexploited distorted 1T ( d 1T) phase. The origin of the ferroelectricity in d 1T-MoTe 2 results from the spontaneous symmetry breaking due to the relative atomic displacements of Mo atoms and Te atoms. Furthermore, a large ON/OFF resistance ratio is achieved in ferroelectric devices composed of MoTe 2 -based van der Waals heterostructure. Our work demonstrates that ferroelectricity can exist in two-dimensional layered material down to the atomic monolayer limit, which can result in new functionalities and achieve unexpected applications in atomic-scale electronic devices.","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["2D Materials and Applications"],"details":null,"provenance":"openalex","attribution":"Abstract of \"Room-temperature ferroelectricity in MoTe2 down to the atomic monolayer limit\" by Shuoguo Yuan, Xin Luo, Hung‐Lit Chan et al., https://doi.org/10.1038/s41467-019-09669-x, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"2d-materials","name":"2D Materials & Van der Waals Heterostructures","domain_slug":"materials"}],"cited_in_dossiers":[]}
