Molecular electronics aims at developing a data processing based on various types of nano-objects (molecules, bio-molecules, nanoparticules, nanotubes of carbon). The implementation of these objects unit by unit and measurements of their transport properties are two central points of this activity. In the case of molecules illustrated on the opposite image, the stake is the control of electrodes separated by 1 to 3 nm and the comprehension of the interface Molecule-Metal.
Cross formed of two carbon nanotubes deposited on silica. The gray bands (150 nm width and height less than 1 nm) are "molecular Scotch tape" allowing the ordering of the nanotubes.
Realisation of devices and circuits containing carbon nanotubes passes by the control of their positioning on a surface. The auto-assembly of nanotubes on a surface locally functionalized chemically is a technique developped at DRECAM. It makes it possible to consider the design of circuits associating such devices.
Single molecule magnets grafted on carbon nanotubes : the first of its kind has been realized at the Molecular Chemistry and Materials Institute in Orsay (CNRS/University of Paris 11) in collaboration with the Institut Lavoisier de Versailles (CNRS/Université de Versailles ... More »
