Using remarkably simple experimental techniques it is possible to gently break a metallic
contact and thus form conducting nanowires. During the last stages of the pulling a neck …

The diffusion model is used to calculate both the time-averaged flow of particles in stochastic
media and the propagation of waves averaged over ensembles of disordered static …

The tight-binding (TB) approach to the modelling of electrical conduction in small structures
is introduced. Different equivalent forms of the TB expression for the electrical current in a …

The shape of metallic constrictions of nanoscopic dimensions (necks) formed using a
scanning tunneling microscope is shown to depend on the fabrication procedure. Submitting …

We have investigated the multiple-event dielectric breakdown of ultra-thin SiO/sub 2/films
used as gate insulators in MOS devices. A theoretical framework, based on the physics of …

We demonstrate the electrical conductance quantization in a Ni nanowire formed in a break
junction between a ferromagnetic Ni wire and a Ni plate in applied magnetic fields. The …

Charge transport characteristics in metal–metal nanocontacts and single molecular
junctions were studied at electrified solid–liquid interfaces employing a scanning tunneling …

The quantum conductance and its classical wave analogue, the transmittance, are given by
the sum of the eigenvalues of the transmission matrix. However, neither measurements nor …

Conductance experiments on Bi nanowires at 4 K, obtained with a scanning tunneling
microscope, are presented. The conductance of these Bi nanocontacts, formed between two …

A detailed analysis of the distribution of conductances P (g) of quasi-one-dimensional
disordered wires in the metal-insulator crossover is presented. P (g) obtained from a Monte …
