Observation of intrinsic crystal phase in bare few-layer CrI₃.

ABSTRACT: Intrinsic structural phase is a crucial foundation for the fundamental physical properties, and for creating innovative devices with unprecedented performances and unique functionalities. Long-range ferromagnetic orders of van der Waals CrI₃ are strongly tied with interlayer stacking orders. However, the intrinsic structure of few-layer CrI₃ still remains elusive; the predicted monoclinic phase has not yet been experimentally detected in bare few-layer CrI₃. Here we uncover the intrinsic structure of few-layer CrI₃ with interlayer antiferromagnetic coupling, which unambiguously show monoclinic stacking in both bare and hBN-encapsulated bilayer and tri-five-layer CrI₃ throughout an entire temperature range from 300 to 10 K.
