Extra‐High Mechanical and Phononic Anisotropy in Black Phosphorus Blisters (Small 45/2023)

Anisotropic Mechanics and Phononics In article number 2301959, Luqi Liu, Zhiping Xu, Zhong Zhang, and co-workers develop a rectangular-shaped bulge device to uniaxially stretch the suspended 2D materials and further serve as a promising platform to detect the orientation-dependent mechanical and physical properties of anisotropic 2D materials. A typical anisotropic 2D material, black phosphorus, is employed as a reference to measure its anisotropic Young's modulus and reveal its orientation-strain-dependent phononic properties.
