Correlated electronic states at domain walls of a Mott-charge-density-wave insulator 1T-TaS2

The electronic states within domain walls in an interacting electronic system remain elusive. Here, Cho et al. report that the domain wall state in a charge-density-wave insulator 1T-TaS2 decomposes into two localized but nonconducting states at the center or edges of domain walls.
