As 2D materials race toward flexible electronics, precisely tailoring their strain fields without cracking crystals remains a grand challenge. Now, a Purdue team led by Prof. Gary J. Cheng and Prof. Wenzhuo Wu demonstrates the first laser-shock imprinting (LSI) on chiral-chain tellurene, revealing orientation-dependent deformation that retains single-crystal integrity while generating dense dislocation networks—offering a universal route for nanoscale strain engineering of anisotropic 2D systems.
