Intercalating palladium into ErTe3 fully suppresses the a-CDW order while residual diffuse scattering at the a-wavevector arises from c-CDW phonon softening.

Claims

C1strongest claim

These findings suggest that the a-CDW is fully suppressed for x ≥ 0.02, and that the residual diffuse scattering at q1^a originates from the partial phonon softening associated with the c-CDW, reflected by the near equality of the absolute size of q1^c and q1^a.

C2weakest assumption

That the near equality of the absolute magnitudes of q1^c and q1^a is sufficient to attribute all residual diffuse scattering at q1^a to c-CDW phonon softening rather than incomplete suppression or other scattering contributions.

C3one line summary

Pd intercalation above x=0.02 suppresses the a-CDW in ErTe3, with residual diffuse scattering at q=(0.29,0,0) arising from partial phonon softening of the c-CDW due to nearly equal wave-vector magnitudes.
