1D Plasticity in Semiconductor Crystals

Yifei Liu, Zhiqiang Gao, Junnan Jiang, Yupeng Ma et autres

The exceptional plasticity recently found in inorganic semiconductors can be classified into two types: the three-dimensional (3D) orientation-insensitive deformability in polycrystals, and the two-dimensional (2D) anisotropic case in layered crystals. It is thus highly anticipated that one-dimensional (1D) plasticity should also exist …
