The influence of partial Nb → Mo substitution in the walls of MoS2 nanotubes of various diameters and atomic configurations (armchair and zigzag) on their electronic structure, structural parameters, and relative stability is exemplified by a series of “mixed” Mo0.9Nb0.1S2 nanotubes. The electronic properties of Mo0.9Nb0.1S2 nanotubes are discussed as a function of the possible types of distribution of doping Nb atoms in the tubes Полный текст |
