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 ...
Electron Tunneling Excitation of a Coupled Two Impurity System
(Springer, 2018)
Kondo effects in individual atoms, molecular magnets or quantum dotshave received a lot of attention. Systems with two units, like double quantum dotsor two atoms, have also attracted some attention due to the interplay ...
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, ...
