Molecular Transport Junctions: Clearing Mists
What is the electronic conductance of a junction containing a single molecule attached at each end to metal electrodes? This simplest of questions in molecular electronics has proved surprisingly difficult to answer. In a 2003 review of the field, Salomon et al. showed that for one simple molecule, 1,8-octanedithiol attached to gold electrodes, the reported experimental values of low-bias condu...
متن کاملTransport through molecular junctions
Exploiting the rich design space of organic molecules for applications in future electronic devices is one of the main challenges in nanotechnology. Several groups have recently demonstrated, for a limited set of molecules, clear single-molecule characteristics and fair agreement with computations. Now that attaching leads to individual molecules has been demonstrated we naturally enter into th...
متن کاملMolecular transport junctions: vibrational effects
Transport of electrons in a single molecule junction is the simplest problem in the general subject area of molecular electronics. In the past few years, this area has been extended to probe beyond the simple tunnelling associated with large energy gaps between electrode Fermi level and molecular levels, to deal with smaller gaps, with near-resonance tunnelling and, particularly, with effects d...
متن کاملMolecular electronics: some views on transport junctions and beyond.
The field of molecular electronics comprises a fundamental set of issues concerning the electronic response of molecules as parts of a mesoscopic structure and a technology-facing area of science. We will overview some important aspects of these subfields. The most advanced ideas in the field involve the use of molecules as individual logic or memory units and are broadly based on using the qua...
متن کاملTime-dependent transport through molecular junctions.
We investigate transport properties of molecular junctions under two types of bias--a short time pulse or an ac bias--by combining a solution for Green's functions in the time domain with electronic structure information coming from ab initio density functional calculations. We find that the short time response depends on lead structure, bias voltage, and barrier heights both at the molecule-le...
