a DOS evolution of the dip in Ta1-δWδSe2 monolayer with δ. The STM images on the right show the corresponding morphology of the layer. b Width vs. δ in the non-superconducting regime. The error bars show the standard error of the mean. c Zoom-in of the dI/dV spectra shown in a illustrating the evolution of the differential conductance towards linearity at high disorder.
