Unraveling the dislocation core structure at a van der Waals gap in bismuth telluride

The atomic level core structure of dislocations in non-metallic materials such as chalcogenides remains elusive. Here, the authors combine atomic-resolution electron microscopy and simulations to image a dislocation core in bismuth telluride and show it spreads because of weak bonding between atomic...
