The Breit-Wigner resonance formula is used to model a class of molecular electronic devices, in order to establish an abstract model for exploration of their applicability in future nanoelectronic systems. The model is used to characterize molecular device I-V curves in terms of the coupling between the molecule and the leads, and demonstrate digital circuit functionality. Circuit metrics such ...

As the dominating CMOS technology is fast approaching a “brick wall,” new opportunities arise for competing solutions. Nanoelectronics has achieved several breakthroughs lately and promises to overcome many of the limitations intrinsic to current semiconductor approaches. Most of the results in this area reported until now focus on devices and interconnect; this work goes several steps further ...

Using molecules as functional units for electronic device application[1] is an interesting perspective and a possible goal of nano-electronics. Work in this field has clearly demonstrated that many of the important molecular device characteristics relate specifically to a strong coupling between the atomic and the electronic degrees of freedom. However, from a theoretical point of view, the acc...

We describe an approach for controlling electrostatic barriers in molecular electronics devices which uses anisotropic dielectric material to modify the analytic form of the effective electrostatic interactions within the device. We study the one-dimensional geometry relevant to interfaces between carbon nanotubes and find that the bound charge induced in a uniaxial dielectric can replace the b...

Bridging the difference in atomic structure between experiments and theoretical calculations and exploring quantum confinement effects in thin electrodes (leads) are both important issues in molecular electronics. To address these issues, we report here, by using Au-benzenedithiol-Au as a model system, systematic investigations of different models for the leads and the lead-molecule contacts: l...

of the thesis The thesis describes the realization of high-performance silicon nanowire (Si NW) logic circuits and a novel surface modification technique for nanoscale electronics applications. First, doped Si NWs were generated via the superlattice nanowire pattern transfer (SNAP) process, forming aligned, uniform, ultra-dense NW arrays. The NWs served as the channel material for field-effect ...

This paper outlines a design paradigm for molecular scale electronic systems. The contrast between the present bulk devices and potential molecular systems is presented along with the limitations of using bulk design philosophies for molecular-sized components. For example, the overwhelming considerations of heat dissipation on molecular scale electronic architectures are shown which demonstrat...

Research of organic molecular electronics has a long history and has developed through several steps of progress. For example, the idea of “molecular electronic devices” was proposed more than 20 years ago and continuous researches have been conducting by many scientists to realize practical applications of the organic molecular devices for cultivating a new era of devices. However, wide applic...

Prefabricated nano-scale structures in which gold electrodes are separated by an insulating core permit self-assembly of a single string "molecular necklace" around its circumference; these devices require no further invasive metal deposition following molecular insertion and exhibit symmetrical current-voltage (I-V) curves that mimic those of self-assembled films on planar substrates.
