Functional molecular electronic devices through environmental control

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...

Exploring coherent transport through π-stacked systems for molecular electronic devices.

Understanding electron transport across π-stacked systems can help to elucidate the role of intermolecular tunneling in molecular junctions and potentially with the design of high-efficiency molecular devices. Here we show how conjugation length and substituent groups influence the electron transport and thermoelectric response in the π-stacked structures by investigating five representative st...
