Electronic properties of armchair transition metal dichalcogenides nanoribbons deposited with atomic chains.

Electronic properties of armchair transition metal dichalcogenides (TMD) nanoribbons bonded with atomic chains are studied using density-functional calculations. The pure armchair TMD nanoribbon with 15 dimer lines possesses non-magnetic band structures with a moderate energy gap. Their edge states near the Fermi level exhibit different kinds of behavior in accordance to the different elements. Energy bands of the deposited atomic chains hybridize with the edge states of the ribbon and induce various magnetic properties, with different locations of deposition taken into account. The results are useful for fabricating novel nanoelectronic devices.
