Novel 2D vanadium sulphides: synthesis, atomic structure engineering and charge density waves
Camiel van Efferen, Joshua Hall, Nicolae Atodiresei +9
Two new ultimately thin vanadium rich 2D materials based on VS2 are created via molecular beam epitaxy and investigated using scanning tunneling microscopy, X-ray photoemission spe…

A full gap above the Fermi level: the charge density wave of monolayer VS2
Camiel van Efferen, Jan Berges, Joshua Hall +15
In the standard model of charge density wave (CDW) transitions, the displacement along a single phonon mode lowers the total electronic energy by creating a gap at the Fermi level,…
