Electronic structure of Graphene/Co interfaces
Daniela Pacilé, Simone Lisi, Iolanda Di Bernardo +12
Photoemission, from core levels and valence band, and low-energy electron diffraction (LEED) have been employed to investigate the electronic and structural properties of novel gra…
Silicene on Ag(111): an honeycomb lattice without Dirac bands
Sanjoy Kr. Mahatha, Paolo Moras, Valerio Bellini +4
The discovery of (4x4) silicene formation on Ag(111) raised the question on whether silicene maintains its Dirac fermion character, similar to graphene, on a supporting substrate.…
Coexistence of multiple silicene phases in silicon grown on Ag(111)
Paolo Moras, Tevfik Onur Menteş, Polina M. Sheverdyaeva +2
Silicene, the silicon equivalent of graphene, is attracting increasing scientific and technological attention in view of the exploitation of its exotic electronic properties. This…
Low-Temperature Insulating Phase of the Si(111)--77 Surface
S. Modesti, P. M. Sheverdyaeva, P. Moras +5
We investigated the electronic structure of the Si(111)--77 surface below 20 K by scanning tunneling and photoemission spectroscopies and by density functional theory calcu…
Systematics of electronic and magnetic properties in the transition metal doped SbTe quantum anomalous Hall platform
M F. Islam, C. M. Canali, A. Pertsova +19
The quantum anomalous Hall effect (QAHE) has recently been reported to emerge in magnetically-doped topological insulators. Although its general phenomenology is well established,…
Magnetic decoupling of ferromagnetic metals through a graphene spacer
I. Grimaldi, M. Papagno, L. Ferrari +4
We study the magnetic coupling between different ferromagnetic metals (FMs) across a graphene (G) layer, and the role of graphene as a thin covalent spacer. Starting with G grown o…
Energy-momentum mapping of d-derived Au(111) states in a thin film
P. M. Sheverdyaeva, R. Requist, P. Moras +5
The quantum well states of a film can be used to sample the electronic structure of the parent bulk material and determine its band parameters. We highlight the benefits of two-dim…
Mesoscopic electron focusing in topological insulators
P. Sessi, P. Rüßmann, T. Bathon +15
The particle wave duality sets a fundamental correspondence between optics and quantum mechanics. Within this framework, the propagation of quasiparticles can give rise to superpos…
Hybridization of Graphene and a Ag Monolayer Supported on Re(0001)
M. Papagno, P. Moras, P. M. Sheverdyaeva +5
We have investigated the electronic structure of graphene supported on Re(0001) before and after the intercalation of one monolayer of Ag by means of angle-resolved photoemission s…
Excitation spectra of transition metal atoms on the Ag (100) surface controlled by Hund's exchange
S. Gardonio, M. Karolak, T. O. Wehling +5
We report photoemission experiments revealing the valence electron spectral function of Mn, Fe, Co and Ni atoms on the Ag(100) surface. The series of spectra shows splittings of hi…
Spectral functions of isolated Ce adatoms on paramagnetic surfaces
S. Gardonio, T. O. Wehling, L. Petaccia +6
We report photoemission experiments revealing the full valence electron spectral function of Ce adatoms on Ag(111), W(110) and Rh(111) surfaces. A transfer of Ce 4f spectral weight…
Correlated Electrons Step-by-Step: Itinerant-to-Localized Transition of Fe Impurities in Free-Electron Metal Hosts
C. Carbone, M. Veronese, P. Moras +10
High-resolution photoemission spectroscopy and realistic ab-initio calculations have been employed to analyze the onset and progression of d-sp hybridization in Fe impurities depos…
