Calculations of the electronic transport in thiol-linked junctions of n-acene molecules
We investigate the transport properties of molecules belonging to the acenes series by using density functional
theory combined with the non-equilibrium Green’s function approach to electronic transport. We calculate...
The theoretical conceptual investigation of intramolecular hydrogen bond strength in the O-H…O=C systems
-3]. In an intramolecular hydrogen bond -IHB- system, both proton donor and proton acceptor groups, which may be of various kinds of functional groups, are located in the same molecule. The cis-enol forms of β-diketone, β-aminoenone, and β-enaminoimine molecules are engaged...
Tunnel Magnetoresistance of an Organic Molecule Junction
related parameters, and depends on: (i) the applied voltages and (ii) the length of
oligophenylele molecule....
Evaluation of electronic and transport properties of a nano-scale device in the presence of electric field
(OSE)
molecule sandwiched between two ferromagnetic electrodes has been carried out. We adopt a modified
Su–Schrieffer–Heeger (SSH) Hamiltonian for describing the isolated Pentathiophene molecule. The
ground state of the molecule...
Beta Viscosit Prescription in Self-Gravitating Disks
Duschl et al. (2000) have shown that the standard model for geometrically
thin accretion disks (®-disks) leads to inconsistency if self-gravity play a role. This
problem arise from parametrization of viscosity ...

ENVIRONMENTAL EFFECTS ON ELECTRIC PROPERTIES OF DNA MOLECULE
We examined here the problem of electronic conduction between two metallic
leads via a DNA molecule. The formal analysis is accomplished through the use of
T-matrix formalism of scattering theory and Löwdin's partitioning technique. We...
Effect of impurity on electron transport through a C60 molecule:study of the role of single and multiple contacts
At the nanoscale, even a single atom change in the structure can noticeably alter the properties, and therefore,
the application space of materials.We examine this behavior of nanomaterials using fullerene as a ...
