TL;DR: Here it is provided compelling evidence, from both structural and electronic properties, for the synthesis of epitaxial silicene sheets on a silver substrate, through the combination of scanning tunneling microscopy and angular-resolved photoemission spectroscopy in conjunction with calculations based on density functional theory.

TL;DR: A giant Rashba-type spin splitting on a semiconducting substrate by means of a Bi-trimer adlayer on a Si(111) wafer with an energy much larger than what has previously been reported for any semiconductor heterostructure is demonstrated.

TL;DR: Systematic analyses of angle-resolved photoemission spectroscopy and X-ray absorption spectra show that these Fröhlich polarons are two- dimensional and only exist with inversion symmetry breaking by two-dimensional oxygen vacancies, providing a rare solvable field theoretical model and suggesting the relevance of large (bi)polarons for superconductivity in perovskite oxides, as well as in high-temperature superconductors.

TL;DR: It is demonstrated that thermal deposition of a monolayer of an elementary reducing agent suffices to create 2DESs in numerous oxides.

TL;DR: In this article, the k-space characteristics of the Kondo-hybridization process are used to unravel the origin of two types of metallic states experimentally observed by angle-resolved photoelectron spectroscopy (ARPES) in the electronic band structure of SmB6(001).
