AB  - We report about results from density functional based calculations on structural, electronic and transport properties of one-dimensional MoS2 nanoribbons with different widths and passivation of their edges. The edge passivation influences the electronic and transport properties of the nanoribbons. This holds especially for nanoribbons with zigzag edges. Nearly independent from the passivation the armchair MoS2 nanoribbons are semiconductors and their band gaps exhibit an almost constant value of 0.42 eV. Our results illustrate clearly the edge priority on the electronic properties of MoS2 nanoribbons and indicate problems for doping of MoS2 nanoribbons.

AB  - We report a systematic research on structural, electronic, and transport properties of a variety of graphene nanoribbon (GNR) break junctions, with different widths and edge chiralities. Our extensive molecular dynamics simulations provide insight into a variety of possible geometries of the break junctions that are obtained by stretching of the graphene ribbons beyond their breaking points. One or more carbon chains can emerge as structural bridges in the junctions. All investigated ruptured systems obey conduction gaps even when their geometries significantly differ by the number of the bridging chains and the variety of their contacts with GNR electrodes.

AB  - The electrical response of graphene-based materials can be tailored under mechanical stress. We report different switching behaviors that take place in mechanically deformed graphene nanoribbons prior to the breakage of the junction. By performing tight-binding molecular dynamics, the study of structural changes of graphene nanoribbons with different widths is achieved, revealing that carbon chains are the ultimate bridges before the junction breaks. The electronic and transport calculations show that binary ON/OFF states can be switched prior to and during breakage depending on the atomic details of the nanoribbon. This work supports the interpretation of recent experiments on nonvolatile memory element engineering based on graphene break junctions.
