The electronic properties of armchair transition metal dichalcogenides (TMD) nanoribbons binding with atomic chains are studied using density-functional calculations. The pure armchair TMD nanoribbons with 15 dimer lines are chosen to investigate and own nonmagnetic band structures with a moderate energy gap. Their edge states near the Fermi level display different kinds of behavior depending on the different combination of elements. The energy bands of atomic chains have the interactions with the edge states from the ribbon and induce various magnetic properties. The stacking locations are also taken into account. The results may be helpful in manufacturing nanoelectronic devices.
