Stability and electronic properties of rhenium sulfide nanotubes

Abstract

The structural properties, the stability and the electronic properties of single-walled ReS2 nanotubes are studied for-the first time using the density-functional tight-binding method (DFTB). It is found, that the properties of these nanotubes are determined essentially by the electronic structure causing unique character of intralayer metal-metal bonding within their walls, which evokes their semiconducting character and the highest stiffness after carbon and BN nanotubes.
