For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Here, fitting parameters A and D are linear and nonlinear drag coefficients, respectively, b is the Burgers vector length, and v 0 a minimum critical velocity for radiative dispersion. It is also ...

Topological lattice defects, such as dislocations and grain boundaries (GBs), are ubiquitously present in the bulk of quantum materials and externally tunable in metamaterials. In terms of robust ...
