Phys.org  March 6, 2023 A class of 3D atomic wires of transition metal chalcogenides (TMC) structures consisting of bundles of TMC nanofibers held together by metallic atoms in between the fibers, all forming a well-ordered lattice in its cross section are of particular interest. Depending on the choice of metal, the structure could even be made to become a superconductor. Researchers in Japan demonstrated versatile method to fabricate indium (In)-intercalated W6Te6 (In–W6Te6) bundles with a nanoscale thickness. Atomic-resolution electron microscopy revealed that In atoms were surrounded by three adjacent W6Te6 wires. First-principles calculations suggested that their wire-by-wire stacking can transform […]
