WSe2 1T′–1H interface electronic structure. a Sketch of the structural model used to theoretically investigate the 1T′–1H interface in single-layer WSe2. The interface position x = 0 is indicated. b Momentum- and spin-resolved LDOS(E) at the 1T′–1H interface shows the dispersion and spin-momentum locking of the interface states (blue/red curves show different spin polarizations). c Energy-resolved LDOS at the 1T′–1H interface (blue curve) in single-layer WSe2 compared to the LDOS at a point well within the 1T′ bulk region (red curve). d Dependence of LDOS at the band gap energy on distance from the 1T–1H interface compared to experimental dI/dV linecut at Vs = −130 mV (from Fig. 5e)
