Antiferromagnetic stripe phase and large-gap insulating ground state of the correlated ~R30-Sn/Si(111) single atomic layer
Mohammadmehdi Torkzadeh, Mattia Iannetti, Mathieu Lizée +10
The one-third monolayer Sn layer on Si(111) has long been considered a benchmark system for exploring two-dimensional Mott physics, owing to its narrow bandwidth and sizable on-sit…
The electronic structure of a doped Mott-Hubbard surface
Mattia Iannetti, Silvio Modesti, Giovanni Di Santo +8
The Sn/Si(111)-({\sqrt}3{\times}{\sqrt}3)R30° surface, a 2D Mott insulator, has long been predicted and then found experimetally to metallize and even turn superconducting upon bor…
On the importance of measuring accurately LDOS maps using scanning tunneling spectroscopy in materials presenting atom-dependent charge order: the case of the correlated Pb/Si(111) single atomic layer
C. Tresca, T. Bilgeri, G. Menard +11
We show how to properly extract the local charge order in two-dimensional materials from scanning tunneling microscopy/spectroscopy (STM/STS) measurements. When the charge order pr…
Can the "shadow" of graphene band clarify its flatness?
Matteo Jugovac, Cesare Tresca, Iulia Cojocariu +6
Graphene band renormalization at the proximity of the van Hove singularity (VHS) has been investigated by angle-resolved photoemission spectroscopy (ARPES) on the Li-doped quasi-fr…
Charge density wave in single-layer Pb/Ge(111) driven by Pb-substrate exchange interaction
Cesare Tresca, Matteo Calandra
Single layer Pb on top of (111) surfaces of group IV semiconductors hosts charge density wave and superconductivity depending on the coverage and on the substrate. These systems ar…
Charge density wave and spin insulating state in single layer 1T-NbS
Cesare Tresca, Matteo Calandra
In bulk samples and few layer flakes, the transition metal dichalcogenides NbS and NbSe assume the H polytype structure with trigonal prismatic coordination of the Nb atom.…
Chiral spin texture in the charge-density-wave phase of the correlated metallic Pb/Si(111) monolayer
C. Tresca, C. Brun, T. Bilgeri +10
We investigate the 1/3 monolayer -Pb/Si(111) surface by scanning tunneling spectroscopy (STS) and fully relativistic first-principles calculations. We study both the high-temper…
