Large fermi surface of heavy electrons at the border of mott insulating state in nis2

HIGHLIGHTS

• who: S. Friedemann from the HH Wills LaboratoryUniversity of London, Egham , EX, UK have published the paper: Large Fermi Surface of Heavy Electrons at the Border of Mott Insulating State in NiS2, in the Journal: Scientific Reports Scientific Reports

SUMMARY

NiS2 can be tuned into the metallic state by hydrostatic pressure, enabling immediate access to the Fermi surface geometry and quasiparticle mass in close proximity to the MIT. Whereas megabar pressures are required to metallize NiO, rendering quantum oscillation measurements impossible with current techniques, the tunability of the sulfur dimer-derived bands in . . .
