Molecular Electronics: Mechanically Controllable Break Junctions for Molecular Electronics (Adv. Mater. 35/2013)

Mechanically controllable break-junctions for use as electrodes for molecular electronics

We discuss the use of mechanically controllable break-junctions (MCBs) as electrodes for contacting individual objects such as clusters or molecules. A big advantage of MCB electrodes is the possibility of varying the contact geometry and, accordingly, the contact resistances and the quantum coherent transport properties between the object under study and the electrodes. We compare the suitabil...

molecular electronics

electron components have been steadily decreasing in size, while molecular materials have in recent years been found to exhibit many of the properties used in electronics. such developments are giving rise to a new field in which molecular materials are used for electronic applications. molecular electronics offers .

Molecular electronics in junctions with energy disorder

We investigate transport through molecular wires whose energy levels are affected by environmental fluctuations. We assume that the relevant fluctuations are so slow that they, within a tight-binding description, can be described by disordered, Gaussian distributed onsite energies. For long wires, we find that the corresponding current distribution can be rather broad even for a small energy va...

Foundations of Molecular Electronics — Charge Transport in Molecular Conduction Junctions

The most fundamental structure involved in molecular electronics is a molecular transport junction, consisting of one (ideally) or more molecules extending between two electrodes. These junctions combine the fundamental process of intramolecular electron transfer with the mixing of molecular and continuum levels at the electrodes and the nonequilibrium process of voltage-driven currents. Much o...
