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

Tetradymite-structured chalcogenides such as bismuth telluride (Bi2Te3) are of significant interest for thermoelectric energy conversion and as topological insulators. Dislocations play a critical role during synthesis and processing of such material

We present a simple exactly solvable model, based on an Anderson-Newns-Grimley type Hamiltonian, for a three-terminal device at molecular level. This device contains two nanowires as source and drain, a scanning tunnelling microscopy (STM) tip as gat

We investigate the structure of the (0001) basal twin boundary in Bi2Te3. Electron diffraction measurements show that this interface corresponds to a 180° rotation of the crystal about the [0001] axis, an alignment that reverses the stacking of the
