Even if Moore’s Law continues to hold, it will take about 250 years to fill the performance gap between present-day computer and the ultimate computer determined from the laws of physics alone. Information processing technology in the post-CMOS era will likely consist of a heterogeneous set of novel device technologies that span a broad range of materials, operational principles, data represent...

Charge transport at the molecular scale builds the cornerstone of molecular electronics (ME), a novel paradigm aiming at the realization of nanoscale electronics via tailored molecular functionalities. Biomolecular electronics, lying at the borderline between physics, chemistry and biology, can be considered as a sub-field of ME. In particular, the potential applications of DNA oligomers either...

Molecular dynamics simulations using ab initio force fields and signal processing techniques are combined to analyze the dynamic properties of a minimum unit of a field programmable random molecular array also called nanocell. We analyze stretching, angular, and torsional internal modes at several temperatures of operation and their correlations as well as the possibility of signal modulation a...

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...

The field of molecular and organic electronics has seen rapid progress in recent years, developing from concept and design to actual demonstration devices in which both single molecules and self-assembled monolayers are employed as light-responsive components. Research in this field has seen numerous unexpected challenges that have slowed progress and the initial promise of complex molecular-ba...

Molecular electronic devices are the upmost destiny of the miniaturization trend of electronic components. Although not yet reproducible on large scale, molecular devices are since recently subject of intense studies both experimentally and theoretically, which agree in pointing out the extreme sensitivity of such devices on the nature and quality of the contacts. This chapter intends to provid...

We describe our research into building integrated molecular electronics circuitry for a diverse set of functions, and with a focus on the fundamental scientific issues that surround this project. In particular, we discuss experiments aimed at understanding the function of bistable rotaxane molecular electronic switches by correlating the switching kinetics and ground state thermodynamic propert...

molecular electronics growing, and prospects of single-molecule electronics improving, there is an increasing need to understand the interactions and electronic structure at interfaces between molecular and nonmolecular phases1-3. The level of activity in new materials for organic light-emitting diodes, organic field-effect transistors, and organic solar cells; optical or transport characteriza...
