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...

We describe how to treat the interaction of traveling electrons with localized vibrational modes in nanojunctions. We present a multichannel scattering technique, which can be applied to calculate the transport properties for realistic systems, and we show how it is related to other methods that are useful in particular cases. We apply our technique to describe recent experiments on the conduct...

The reduction of feature size on chips achieved by the tremendous technological advances in miniaturization that have enabled more and more transistors to be packed onto a silicon chip is limited not just by the resolution of the beam optics and resist chemistry, but also by the problem of inevitable fluctuations, both quantum and classical. Consequently, below a limiting dimension that we have...

Advances in our basic scientific understanding at the molecular and atomic level place us on the verge engineering designer structures at the molecular scale. This introduces exciting opportunities to design computing systems at what may be the ultimate limits on device size. At this scale, we are faced with new challenges and a new cost structure which motivate different computing architecture...

This study details a modular and general synthesis of a new class of molecules consisting of cruciform pi-systems. The key to synthesizing these molecules was an unprecedented double Staudinger cyclization. Once formed, these rigid compounds assemble into ordered monolayer films on metal and metal oxide surfaces to orient their conjugated, bis-phenyloxazole subunits upright. This surface orient...

Since the first measurement of electron tunneling through an organic monolayer in 1971,(Mann and Kuhn, 1971) and the gedanken experiment of a molecular current rectifying diode in 1974,(Aviram and Ratner, 1974) molecular-scale electronics have attracted a growing interest, both for basic science at the nanoscale and for possible applications in nano-electronics. In the first case, molecules are...

This research paper is proposing the idea of pseudo code representation to molecular programming used in designing molecular electronics devices. Already the schematic representation of logical gates like AND, OR, NOT etc.from molecular diodes or resonant tunneling diode are available. This paper is setting a generic pseudo code model so that various logic gates can be formulated. These molecul...

Molecular electronics [1] aims to use molecules as building blocks for the fabrication of electronic components—diodes, switches, transistors, and the like. At the heart of this idea is the possibility of synthesizing organic molecules with tailored properties, manipulating their electronic structure and optimizing their binding to different surfaces. Devices as small as a few molecules might l...

Chemically assembled electronic nanotechnology (CAEN) is a promising alternative to CMOS-based computing. However, CAEN-based circuits are expected to have huge defect densities. To solve this problem CAEN can be used to build reconfigurable fabrics which, assuming the defects can be found, are inherently defect tolerant. In this paper, we propose a scalable testing methodology for finding defe...

We present results on a new fullerene-based anchoring group for molecular electronics. Using lithographic mechanically controllable break junctions in vacuum we have determined the conductance and stability of single-molecule junctions of 1,4-bis(fullero[c]pyrrolidin-1-yl)benzene. The compound can be self-assembled from solution and has a low-bias conductance of 3 x 10(-4) G0. Compared to 1,4-b...
