Self-Assembled CNT-Based Electronic Devices

Self-assembled monolayer-based selective modification on polysilicon nanobelt devices.

In this study, a self-assembled monolayer (SAM) of methoxy-poly (ethylene-glycol)-silane (mPEG-sil) was used to modify the silicon dioxide surface of polysilicon nanodevices (PNDs) to act as a passivation layer that inhibits nonspecific binding of proteins and reduces localized Joule heating power. Selective modifications of 3-aminopropyltrimethoxysilane (APTMS), NHS-biotin and dye-labeled Stre...

Self-assembled DNA Nanostructures and DNA Devices

This chapter overviews the past and current state of the emerging research area in the field of nanoscience that make use of synthetic DNA to self-assemble into DNA nanostructures and to make operational molecular-scale devices. Recently there have been a series of quite astonishing experimental results which have taken the technology from a state of intriguing possibilities into demonstrated c...

Electronic transport in self-assembled alkanethiol monolayers

Electron tunneling through self-assembled monolayers of alkanethiols is investigated. Temperature-dependent current– voltage measurements are performed to distinguish between di erent conduction mechanisms. Temperature-independent electron transport is observed, proving direct tunneling as the dominant conduction mechanism of alkanethiols. An exponential dependence of tunneling current on molec...

Electronic structure of self-assembled amorphous polyfluorenes.

We investigate the role of conformational disorder and intermolecular interactions on the electronic structure of amorphous clusters of polyfluorenes. Classical molecular dynamics simulations are used to determine probable molecular geometries and chain packing, and first-principles density functional theory calculations are employed to determine electronic structure and orbital localization pr...
