Coulomb and tunneling-coupled trilayer systems at zero magnetic field
(American Physical Society, 2016-02)
The ground-state electronic configuration of three coupled bidimensional electron gases has been determined using a variational Hartree-Fock approach, at zero magnetic field. The layers are Coulomb coupled, and tunneling ...
Periodically rippled graphene: growth and spatially resolved electronic structure
(American Physical Society, 2008-12)
We grow epitaxial graphene monolayers on Ru(0001) that cover uniformly the substrate over lateral distances larger than several microns. The weakly coupled graphene monolayer is periodically rippled and it shows charge ...
Inelastic electron excitation of transition metal atoms and Kondo resonances
(Elsevier Academic Press Inc, 2019-01)
An ionic Hamiltonian based on the first Hund rule applied to transition metal atoms is reviewed and discussed in detail. The tunneling current between a STM-tip and a transition metal atom is analyzed by means of that ...
Electron tunneling at the molecularly thin 2D perovskite and graphene van der Waals interface
(Nature Publishing Group, 2020-10)
Quasi-two-dimensional perovskites have emerged as a new material platform for optoelectronics on account of its intrinsic stability. A major bottleneck to device performance is the high charge injection barrier caused by ...
Signatures of tunneling and multiphoton ionization by short-laser pulses: The partial-wave distribution
(Institute of Physics Publishing, 2015-12)
We analyze the two-dimensional angular momentum-energy distribution of electrons emitted from argon by short laser pulses. We identify characteristic features of both multiphoton and tunneling ionization in the partial-wave ...
Tunneling conductance of long-range Coulomb interacting Luttinger liquid
(American Physical Society, 2020-05)
The theoretical model of the short-range interacting Luttinger liquid predicts a power-law scaling of the density of states and the momentum distribution function around the Fermi surface, which can be readily tested through ...
Electrochemical scanning tunneling spectroscopy of redox-active molecules bound by Au-C bonds
(American Chemical Society, 2010-02)
(Figure Presented) A comparison of the electrochemical gating of molecular conduction by a redox [Os(bipyridine)(pyridine)Cl] complex tethered to Au(111) with two different metal-molecule junctions in a scanning tunneling ...
Transport properties of Cu-AlF 3 -W and Cu-AlF 3 -Cu heterojunctions using STS measurements and a DFT-NEGF approach
(Elsevier B.V., 2018-09)
To understand and to analyze the transport properties of different metal-insulator systems, we developed an experimental study of the electronic transport properties of AlF 3 thin films deposited over a Cu(1 0 0) substrate, ...
Indium Tin Oxide optical access for magnetic tunnel junctions in hybrid spintronic-photonic circuits
(IOP Publishing, 2020-10)
The all-optical magnetization reversal of magnetic layers, by picosecond optical pulses, is of particular interest as it shows the potential for energy-efficient and fast magnetic tunnel junction (MTJ) elements. This ...
Signatures of tunneling and multiphoton ionization in the electron-momentum distributions of atoms by intense few-cycle laser pulses
(American Physical Society, 2006-12)
Electron-momentum distributions for above-threshold ionization of argon in a few-cycle, linearly polarized laser pulse are investigated. Spectral features haracteristic of multiphoton as well as tunneling ionization coexist ...
