Tuning the conductance of a molecular switch
Miriam del Valle, Rafael Gutierrez, Carlos Tejedor +1
The ability to control the conductance of single molecules will have a major impact in nanoscale electronics. Azobenzene, a molecule that changes conformation as a result of a tran…
Giant magnetoresistance of multiwall carbon nanotubes: modeling the tube/ferromagnetic-electrode burying contact
S. Krompiewski, R. Gutierrez, G. Cuniberti
We report on the giant magnetoresistance (GMR) of multiwall carbon nanotubes with ultra small diameters. In particular, we consider the effect of the inter-wall interactions and th…
Interference Blockade in the Conductance of Organic Molecules
R. Gutierrez, F. Grossmann, R. Schmidt
The conductance of {\em cis/trans} isomers of stilbene molecules connected to armchair single wall carbon nanotubes is studied in the Landauer formalism combined with a density-fun…
The role of contacts in molecular electronics
G. Cuniberti, F. Grossmann, R. Gutierrez
Molecular electronic devices are the upmost destiny of the miniaturization trend of electronic components. Although not yet reproducible on large scale, molecular devices are since…
Fullerene based devices for molecular electronics
G. Cuniberti, R. Gutierrez, G. Fagas +3
We have investigated the electronic properties of a C_60 molecule in between carbon nanotube leads. This problem has been tackled within a quantum chemical treatment utilizing a de…
