Autor: Josu Diego, A. H. Said, S. K. Mahatha, Raffaello Bianco, Lorenzo Monacelli, Matteo Calandra, Francesco Mauri, K. Rossnagel, Ion Errea, S. Blanco-Canosa

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)

The nature of the charge density wave transition in VSe2 is still debated. Here, the authors demonstrate that the transition is mainly driven by electron-phonon interactions, despite the presence of the Fermi-surface nesting, and that Wan-der-Waals f

Review of scientific instruments 92(5), 053703 (2021). doi:10.1063/5.0046567
The performance of time-resolved photoemission experiments at fs-pulsed photon sources is ultimately limited by the e–e Coulomb interaction, downgrading energy and mo

Understanding of charge-density wave (CDW) phases is a main challenge in condensed matter due to their presence in high-Tc superconductors or transition metal dichalcogenides (TMDs). Among TMDs, the origin of the CDW in VSe2 remains highly debated. H

We report the discovery of a nearly-free electronlike resonant state for a ?-Si3N4(0001)-8×8 layer grown on Si(111), as observed by angle-resolved photoemission and scanning tunneling spectroscopy. Comparison with measurements performed on a Si(111)

Unoccupied electronic structure of graphite probed by angle-resolved photoemission spectroscopy

Autor: S. K. Mahatha Krishnakumar, Balasubramanian Thiagarajan, S. R. Menon

Publikováno v: Physical Review B. 84

We report the observation of anomalous bands in graphite valence band structure in angle-resolved photoemission spectroscopy (ARPES) experiments. The photon energy dependence of these bands shows a constant kinetic energy nature. Our results are supp
