Palladium electrodes for molecular tunnel junctions.
Gold has been the metal of choice for research on molecular tunneling junctions, but it is incompatible with complementary metal-oxide-semiconductor fabrication because it forms deep level traps in silicon. Palladium electrodes do not contaminate silicon, and also give higher tunnel current signals in the molecular tunnel junctions that we have studied. The result is cleaner signals in a recog...
متن کاملSupporting Informations for Dynamic constitutional electrodes-toward functional fullerene wires
Materials and Methods: Ruthenium hexamine chloride, Fullerene, C60, cetyltrimethylammonium bromide (CTAB), Tetraethoxysilane (TEOS, 98%), chloroform and toluene were obtained from Sigma and used as received. Ethanol (95–96%, Carlo Erba) and HCl (36%, Prolabo) were used for precursor hydrolysis and film deposition. TBAPF6 (Aldrich) was dried for 6 h in vacuum before use. Sodium nitrate was obtai...
متن کاملDetermining Potentials of Zero Charge of Metal Electrodes versus the Standard Hydrogen Electrode from Density-Functional-Theory-Based Molecular Dynamics.
We develop a computationally efficient scheme to determine the potentials of zero charge (PZC) of metal-water interfaces with respect to the standard hydrogen electrode. We calculate the PZC of Pt(111), Au(111), Pd(111) and Ag(111) at a good accuracy using this scheme. Moreover, we find that the interface dipole potentials are almost entirely caused by charge transfer from water to the surfaces...
متن کاملMolecular nano-junctions formed with different metallic electrodes
Issue no Total pages First page Last page File name Date req Artnum Cover date Abstract Conductance of nanoscale junctions consisting of a molecular monolayer in contact with different metal electrodes is studied. The characteristic energy scales of conductance are determined from the temperature dependence and from the non-linear current–voltage characteristics. Conductance measured at small b...
متن کاملModels of electrodes and contacts in molecular electronics.
Bridging the difference in atomic structure between experiments and theoretical calculations and exploring quantum confinement effects in thin electrodes (leads) are both important issues in molecular electronics. To address these issues, we report here, by using Au-benzenedithiol-Au as a model system, systematic investigations of different models for the leads and the lead-molecule contacts: l...
