The conventional VLSI technology based on lithography is reaching its limits and the extension of Moore’s Law for small-scale conventional silicon based integrated circuits is gaining significance. Developments in the area of molecular electronics devices offer an alternative approach to overcome this problem and have the potential to miniaturize the computational devices down to few nm. This i...

Metal-molecule-metal junctions are the key components of molecular electronics circuits. Gaining a microscopic understanding of their conducting properties is central to advancing the field. In the present contribution, we highlight the fundamental differences between single-molecule and ensemble junctions focusing on the fundamentals of transport through molecular clusters. In this way, we elu...

We present insights into the lead-molecule coupling scheme in molecular electronics junctions. Using a "site-to-state" transformation that provides direct access to the coupling matrix elements between the molecular states and the eigenstate manifold of each lead, we find coupling bands whose character depends on the geometry and dimensionality of the lead. We use a standard tight-binding model...

DNA is a promising molecule for applications in molecular electronics because of its unique electronic and self-assembly properties. Here we report that the conductance of DNA duplexes increases by approximately one order of magnitude when its conformation is changed from the B-form to the A-form. This large conductance increase is fully reversible, and by controlling the chemical environment, ...

The adsorption of a number of amino acids on a defected single-walled carbon nanotube (SWCNT) isinvestigated by using the density-functional theory (DFT) calculations. The adsorption energies andequilibrium distances are calculated for various configurations such as amino acid attaching to defectsites heptagon, pentagon and hexagon in defective tube and also for several molecular orientationswi...

Controlling the charge state of a molecule wired in two-terminal single-molecule junction at room temperature is key challenge molecular electronics relation to development memory and other computational componentry.
