Introduction to Molecular Electronic Devices

Integrating reaction chemistry into molecular electronic devices.

This Focus Review provides an overview of the design and fabrication of new families of molecular electronic devices where reaction chemistry is an efficient means for covalently bridging the nanogaps between separated contacts. In each case ever-reducing top-down device fabrication existing in the silicon-based semiconductor industry is tailored to meet the requirements of ever-expanding lengt...

Molecular Organic Semiconductors for Electronic Devices

Reversible switching in molecular electronic devices.

This manuscript compares the conductance when molecules connecting single-walled carbon nanotubes (SWNTs) change their states of conjugation. We use electrodes made by excising a nanoscale section from an individual SWNT, having shown previously that this is a general method to wire a small number (<10) of molecules into electrical circuits (Figure 1A).1-3 These SWNT molecular devices can be ma...

Molecular Electronic Devices based on Carotenoid Derivatives

The production of devices in nanoscale with specific molecular rectifying function is one of the most significant goals in state-of-art technology. In this work we show by ab initio quantum mechanics calculations coupled with non-equilibrium Green function, the design of an organic two-terminal device. These molecular structures have molecular source and drain with several bridge length (from f...

Introduction to Electronic Structure Theory

Electronic Structure Theory describes the motions of electrons in atoms or molecules. Generally this is done in the context of the Born-Oppenheimer Approximation, which says that electrons are so much lighter (and therefore faster) than nuclei that they will find their optimal distribution for any given nuclear configuration. The electronic energy at each nuclear configuration is the potential ...
