Query: Emergent Novel Metallic State in a Disordered 2D Mott Insulator   It is well established that for non-interacting electrons, increasing
disorder drives a metal into a gapless localized Anderson insulator. While in
three dimensions a threshold in disorder must be crossed for the transition, in
two dimensions and lower, the smallest amount of disorder destabilizes the
metal. The nature of the metal-insulator transition in an interacting system
remains unresolved. Here we explore the effect of disorder on a strongly
correlated Mott insulator without changing the carrier concentration. Angle
resolved photoemission spectroscopy (ARPES) measurements on copper intercalated
single crystals of the layered dichalcogenide 1T-TaS2 reveal the presence of
new delocalized states within the Mott gap. This is the first experimental
realization of a novel disorder-induced metal that was theoretically predicted
to exist between the Mott insulator and Anderson insulator.
