Strong-coupling analysis of scanning tunneling spectra in Bi2Sr2Ca2Cu3O10 + y (Bi-2223)
(American Physical Society, 2013-07-29)
We study a series of spectra measured in the superconducting state of optimally-doped Bi-2223 by scanning-tunneling spectroscopy. Each spectrum, as well as the average of spectra presenting the same gap, is fit using a ...
Surface roughness and surface-induced resistivity of gold films on mica: Application of quantitative scanning tunneling microscopy
(2000)
We report measurements of the resistivity (Formula presented) of a gold film 70 nm thick deposited on mica preheated to 300 °C in UHV, performed between 4 and 300 K, and measurements of the surface topography of the same ...

Resistivity of thin gold films on mica induced by electron–surface scattering: Application of quantitative scanning tunneling microscopy
(Elsevier, 2012)
We report a comparison between the resistivity measured on thin gold films deposited on mica, with
predictions based upon classical theories of size effects (Drude’s, Sondheimer’s and Calecki’s), as well as
predictions ...
Derivation of the spin Hamiltonians for Fe in MgO
(IOP Publishing, 2015-03)
A method to calculate the effective spin Hamiltonian for a transition metal impurity in a non-magnetic insulating host is presented and applied to the paradigmatic case of Fe in MgO. In the first step we calculate the ...
Temperature impact on the tunnel fet off-state current components
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-12)
In this work, the temperature impact on the off-state current components is analyzed through numerical simulation and experimentally. First of all, the band-to-band tunneling is studied by varying the underlap in the ...
A study of transit times in Dirac tunneling
(Iop Publishing LtdBristolInglaterra, 2013)
Metallic states in Topological Insulators with Magnetic Impurities.
(The American Physical SocietyMaryland, 2013-03)
Topological insulators are characterized by an insulating bulk, and an odd number of Dirac cones in the surface. Their existence are due a band inversion in the bulk phase created by a strong spin orbit coupling. Those ...
Inelastic tunneling spectroscopy for magnetic atoms and the Kondo resonance
(IOP Publishing, 2013-04)
The interaction between a single magnetic atom and the metal environment (including a magnetic field) is analyzed by introducing an ionic Hamiltonian combined with an effective crystal-field term, and by using a Green-function ...
Hopping-tunneling model to describe electric charge injection at metal/organic semiconductor heterojunctions
(Wiley-Blackwell, 2015-02-01)
This paper describes a theoretical model which takes into account charge injection by thermally stimulated hopping (HP), as proposed by Arkhipov, and Fowler-Nordheim tunneling (FNT), for steady-state response of a metal/organic ...
