Extended Data Fig. 5: Voigt profile fits to 57° WSe₂/ MoSe₂ UED data.

Profiles are taken from lineouts labelled in Extended Data Fig. 1(b), and indicate an alternative way to estimate the diffraction intensity compared to the method employed in the main text (summing counts within a region of interest). The choice of estimation technique does not change the main findings we report. (a) Example Voigt profile fit to satellite diffraction features. (b) Time series of Voigt-profile peaks fit to satellite diffraction features. Lines connecting data points are only a guide for the eye. (c) Example Voigt profile fit to atomic-scale Bragg diffraction features. (d) Time series of Voigt-profile peaks fit to atomic-scale Bragg diffraction features. Lines connecting data points are only a guide for the eye. (e)-(f) Time series of Voigt profile full-widths-at-half-maximum.
