High-throughput screening of 2D van der Waals crystals with plastic deformability.

ABSTRACT: Inorganic semiconductors exhibit multifarious physical properties, but they are prevailingly brittle, impeding their application in flexible and hetero-shaped electronics. The exceptional plasticity discovered in InSe crystal indicates the existence of abundant plastically deformable two-dimensional van der Waals (2D vdW) materials, but the conventional trial-and-error method is too time-consuming and costly. Here we report on the discovery of tens of potential 2D chalcogenide crystals with plastic deformability using a nearly automated and efficient high-throughput screening methodology. Seven candidates e.g., famous MoS₂, GaSe, and SnSe₂ 2D materials are carefully verified to show largely anisotropic plastic deformations, which are contributed by both interlayer and
