As symmetry-breaking interfaces, edges inevitably influence material properties, particularly for low-dimensional materials such as two-dimensional (2D) graphene and black phosphorus (BP). Hence, exploiting pristine edge structures and the associated edge reconstruction is important. In this study, we revealed edge reconstruction and evolution in monolayer BP (ML-BP) via in situ high-resolution transmission electron microscopy.

The chalcogen compositions of the MoS2 x Se2(1- x ) nanotubes are controllable by adjusting the selenization temperature and duration while the expanded (002) interlayer spacing varies from 0.98 to 0.

- Researchers have created stable metallic 1T-WS2 nanoribbons with unique zigzag chain structures using a simple bottom-up technique, enhanced by ammonia-ion intercalation.
- These nanoribbons exhibit distinct atomic arrangements that lead to unique electrical and optical properties, which differ significantly from those of semiconducting 2H-WS2.
- The study supports the relationship between these specific structures and their properties through theoretical calculations.
