Information Coding for Intramolecular Integration of Logic Functionality
Although molecular electronics has a great potential, the feasibility of this technology will be however conditioned by the possibility of building complex circuits. But while on the technological versant rapid progresses have been accomplished during [...]
Application of Nano-carbon Cold Cathodes for Lighting Elements
In our recent publications it was reported about intensive field emission (FE) of electrons from nano-carbon (nC) thin film material grown by non-catalytic CVD method. The low FE threshold (less than 1.5 V/mm), high density [...]
Variation of Contact Barrier Height in Metal-Semiconducting Carbon Nanotube Junctions using a Localized Gate
We have previously succeeded in modulating current in a carbon nanotube FET device due to the presence of a potential on an AFM tip. Symmetric I-V is observed with no tip, however, the tip has [...]
Effects of Backbone Disorder on Electronic Transport in DNA Molecules
A minimal model was recently proposed to explain the gap opening and the semi-conductor behavior in poly(G)-poly(C) DNA molecules. In this model, the large band gap is attributed to the hybridization of the G-G p [...]
Current Collapse in Tunnelling Transport through Benzene
Single molecule electronic devices offer exciting perspectives for further minituarization of electronic circuits with a potentially large impact in applications. Several experiments have demonstrated the possibility to attach individual molecules to leads and to measure [...]
Effects of Gold Contacts on Transport through Benzene Molecule
Miniaturization of electronic devices has resulted in intensive interest in molecular devices that basically consist of a group of a few atoms, in contrast to the previous ‘bulk’ materials. As the molecules that are to [...]
Theoretical Analysis of Donor – Spacer – Acceptor Structure Molecule for Stable Molecular Rectifier
Mizuseki H., Niimura K., Majumder C., Belosludov R.V., Farajia A.A., Kawazoe Y., Institute for Materials Research, Tohoku University, JP
Recently, the field of molecular electronics has attracted strong attention as a post-silicon technology to enable future nanoscale electronic devices. The realization of a molecular device with a unimolecular rectifying function is one of the [...]
Electrical Transport through Single-molecule Junctions: From molecular orbitals to conduction channels
Present trends in the miniaturization of electronic devices suggest that ultimately single molecules may be used as electronically active elements in a variety of applications. Recent advances in the manipulation of single molecules now permit [...]
Convergence Issues in Ab-initio Transport Calculation through Oxide Barriers and Molecules
Ab-initio calculations of transport through nanometer scale structures, such as individual atoms or molecules and ultra-thin oxide barriers directly link atomic structure and chemistry, which are difficult to probe, to transport properties, which are easier [...]
