Strong magnetic proximity effect in Van der Waals heterostructures driven by direct hybridization
C. Cardoso, A. T. Costa, A. H. MacDonald +1
We propose a new class of magnetic proximity effects based on the spin dependent hybridization between the electronic states at the Fermi energy in a non-magnetic conductor and the…
Efficient GW calculations via the interpolation of the screened interaction in momentum and frequency space: The case of graphene
Alberto Guandalini, Dario A. Leon, Pino D'Amico +4
The GW self-energy may become computationally challenging to evaluate because of frequency and momentum convolutions. These difficulties were recently addressed by the development…
Efficient full frequency GW for metals using a multipole approach for the dielectric screening
Dario A. Leon, Andrea Ferretti, Daniele Varsano +2
The properties of metallic systems with important and structured excitations at low energies, such as Cu, are challenging to describe with simple models like the plasmon pole appro…
Graphene decoupling through oxygen intercalation on Gr/Co and Gr/Co/Ir interfaces
Dario A. Leon, Andrea Ferretti, Daniele Varsano +2
We perform a density functional theory study of the effects of oxygen adsorption on the structural and electronic properties of Gr/Co(0001) and Gr/Co/Ir(111) interfaces. In both in…
Black Phosphorus n-type doping by Cu: a microscopic surface investigation
Abhishek Kumar, Francesca Telesio, Deborah Prezzi +8
We study surface charge transfer doping of exfoliated black phosphorus (bP) flakes by copper using scanning tunneling microscopy (STM) and spectroscopy (STS) at room temperature. T…
Frequency dependence in GW made simple using a multi-pole approximation
Dario A. Leon, Claudia Cardoso, Tommaso Chiarotti +3
In the approximation, the screened interaction is a non-local and dynamical potential that usually has a complex frequency dependence. A full description of such dependenc…
Narrowing of d bands of FeCo layers intercalated under graphene
Daniela Pacilè, Claudia Cardoso, Giulia Avvisati +7
We report on the electronic properties of an artificial system obtained by the intercalation of equiatomic FeCo layers under graphene grown on Ir(111). Upon intercalation, the FeCo…
Magnetic response and electronic states of well defined Graphene/Fe/Ir(111) heterostructure
Claudia Cardoso, Giulia Avvisati, Pierluigi Gargiani +7
We investigate a well defined heterostructure constituted by magnetic Fe layers sandwiched between graphene (Gr) and Ir(111). The challenging task to avoid Fe-C solubility and Fe-I…
Ferromagnetic and Antiferromagnetic Coupling of Spin Molecular Interfaces with High Thermal Stability
Giulia Avvisati, Claudia Cardoso, Daniele Varsano +3
We report an advanced organic spin-interface architecture with magnetic remanence at room temperature, constituted by metal phthalocyanine molecules magnetically coupled with Co la…
Interplay between interlayer exchange and stacking in CrI bilayers
D. Soriano, C. Cardoso, J. Fernández-Rossier
We address the interplay between stacking and interlayer exchange for ferromagnetically ordered CrI, both for bilayers and bulk. Whereas bulk CrI is ferromagnetic, both mag…
FePc Adsorption on the Moiré Superstructure of Graphene Intercalated with a Co Layer
Giulia Avvisati, Simone Lisi, Pierluigi Gargiani +8
The moiré superstructure of graphene grown on metals can drive the assembly of molecular architectures, as iron-phthalocyanine (FePc) molecules, allowing for the production of arti…
Van der Waals spin valves
C. Cardoso, D. Soriano, N. A. García-Martínez +1
We propose spin valves where a 2D non-magnetic conductor is intercalated between two ferromagnetic insulating layers. In this setup, the relative orientation of the magnetizations…
Bright electroluminescence from single graphene nanoribbon junctions
Michael C. Chong, Nasima Afshar-Imani, Fabrice Scheurer +4
Thanks to their highly tunable band gaps, graphene nanoribbons (GNRs) with atomically precise edges are emerging as mechanically and chemically robust candidates for nanoscale ligh…
