Molecular electronics as technology using single molecule, small group of molecules, carbon nanotubes or semiconductor to perform electronic function.
One reason it's tricky to make and hook up nanowires, made of single-crystal silicon, or nanotubes, made of molecule-thick sheets of carbon, is that they are fragile and can easily break when transported from one substrate to another.
According to Loiseau, "In composites it is necessary for the carbon, graphene or nanotube molecules to 'touch' each other to be conductive.
Possible mechanisms are charge transfer between adsorbed gas molecules and the nanotubes or gas-induced changes at the interface between the nanotubes and their metal contacts.
While working to come up with a new technique for synthesizing straw-shaped carbon molecules called nanotubes, Rode got a bit of a frothy surprise.
Since the discovery of carbon nanotubes (CNTs) [2], extensive studies have been carried out on experimental and computing modeling approaches to investigate the physisorption and storage of small molecules in nanotubes [3, 4, 5, 6, 7, 8, 9, 10].
The understanding of the kinetic growth mechanisms of Au on mica allows to tune the process parameters (substrate temperature, pressure, rate deposition, film thickness) to obtain ultra-flat Au film as suitable platform for anchoring self-assembling monolayers (due to Au affinity to thiol groups of organic molecules), molecules, nanotubes, nanoparticles and so on.
The interaction energy of van der Waals (vdW) and coulombic energies at the interface between water molecules and the first cyclic peptide cage suggested that hydrophobic modified functional groups reduced the interior affinity between water molecules and nanotubes, which made it difficult for water molecules to enter a nanotube.
Thus, taking into account the above considerations, we have chosen the smallest fullerene C20 and the magnetic endofullerene Fe@C20 to investigate changes in the dynamical behaviour of molecules inside nanotubes at the Peierls transition.
The presence of MWCNTs in water is evidenced by Raman spectra and the attachment of dye molecules to nanotubes is suggested by analysis of transmission electron microscope images.
