First Princiles Study of the Electron Transport Properties of Buthane-dithiol Nano-Molecular Wire

We report a first-principles study of electrical transport in a single molecular conductor consisting of a buthane-dithiol sandwiched between two Au (100) electrodes. We show that the current was increased by increasing of the external voltage biases. The projected density of states (PDOS) and transmission coefficients (T(E)) under various external voltage biases are analyzed, and it suggests t...

Impact of Anchoring Groups on Ballistic Transport: Single Molecule vs Monolayer Junctions

Tuning the transport properties of molecular junctions by chemically modifying the molecular structure is one of the key challenges for advancing the field of molecular electronics. In the present contribution, we investigate current-voltage characteristics of differently linked metal-molecule-metal systems that comprise either a single molecule or a molecular assembly. This is achieved by empl...
