Abstract Understanding dislocation behaviors in two-dimensional materials is crucial since it influences not only the structural stability of materials, but also functional properties. By combining in situ and aberration corrected transmission electron microscope characterizations in Sb2Te3, it was observed that hot deformation introduced large density of anti-phase boundaries, forcing dislocations to climb. Consequently, the glide of dislocations can break the constraint of localized planer slip in layered structure, increasing the possibility of dislocation interaction and multiplication. The deformability of hot-deformed material is strongly increased.
