Scatter Plot from Scientific Research

The q-independent broadening of the CDW-1 peak spread, Γ0 (T), extracted by fitting their Γq values to a quadratic function of q (equation (2)) for x = 2.0%. The symbols give the fit estimate, and the error bars give the 95% confidence bounds on Γ0 estimated from 3,688 (2.0%) peaks. The dashed lines are a phenomenological fitting function (equation (3)) to extract CDW-1 Bragg glass temperature TBG1. The dotted lines mark the resolution limit Γ from the fit. We find a Bragg glass regime for the x = 2.0% samples by extracting TBG1 (vertical solid lines) from extrapolating the broadening regime to zero spread.
