Single-walled TMD nanotubes (SW-TMDNTs) are 1D materials that can exhibit tunable electronic properties depending on both their chirality and composition. However, much less has been explored about their geometrical structures and chemical variations due to their instability under ambient conditions. Researchers in Japan have shown that the outer surfaces and inner cavities of the BNNTs promote and stabilize the coaxial growth of SW-TMDNTs with various diameters, including few-nanometers-wide species. The chiral indices of individual SW-MoS2NTs were assigned by high-resolution transmission electron microscopy, and statistical analyses revealed a broad chirality distribution ranging from zigzag to armchair configurations. According to the researchers this methodology can be applied to the synthesis of various TMDNTs and provides a universal platform to characterize the chirality-dependent properties of 1D nanotubes with various electronic structures… read more.
