Fano fingerprints of Majoranas in Kitaev dimers of superconducting adatoms
(Elsevier B.V., 2016-09-01)
We investigate theoretically a Fano interferometer composed by STM and AFM tips close to a Kitaev dimer of superconducting adatoms, in which the adatom placed under the AFM tip, encloses a pair of Majorana fermions (MFs). ...
Diffusion of fluorine adatoms on doped graphene
(American Institute of Physics, 2014-09)
We calculate the diffusion barrier of fluorine adatoms on doped graphene in the diluted limit using Density Functional Theory. We found that the barrier D strongly depends on the magnitude and character of the graphene’s ...
Spin-resolved local density of states for an Anderson adatom in a ferromagnetic island
(2013-06-01)
In this work, we investigate theoretically the spin-resolved local density of states (SR-LDOS) of a ferromagnetic (FM) island hybridized with an adatom, which is described by the Single Impurity Anderson Model (SIAM). Our ...
Fe adatoms along Bi nanolines on H/Si(001)
(AMER INST PHYSICS, 2006-08-28)
The stability and electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bi-line nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations. Our results show that ...
Fe adatoms along Bi lines on H/Si(001): Patterning atomic magnetic chains
(2006-08-07)
The stability, electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bilines
nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations.
Our results show that Fe ...
Spin-dependent beating patterns in thermoelectric properties: Filtering the carriers of the heat flux in a Kondo adatom system
(Amer Physical Soc, 2014-11-20)
We theoretically investigate the thermoelectric properties of a spin-polarized two-dimensional electron gas hosting a Kondo adatom hybridized with a STM tip. Such a setup is treated within the single-impurity Anderson model ...
Electrocatalytic effect of Pb and Sn adatoms on the oxidation of 1-propanol on platinized platinum electrodes: Determination of the apparent activation energy
(R Oldenbourg Verlag, 2003-01-01)
The electrocatalytic oxidation of 1-propanol was investigated on platinum electrodes modified by submonolayers of Pb and Sn in acid media. An increase of oxidation rates observed for both Pb and Sn, and the influence of ...
Scanning tunneling microscope operating as a spin diode
(AMER PHYSICAL SOC, 2011)
We theoretically investigate spin-polarized transport in a system composed of a ferromagnetic scanning-tunneling-microscope (STM) tip coupled to an adsorbed atom (adatom) on a host surface. Electrons can tunnel directly ...
