Extended Data Fig. 5: Phonon map of QD side.
From: Nanoscale imaging of phonon dynamics by electron microscopy
a, Spatial mapping of Si phonon peak intensity of the side of a QD. b, Integrated line profile of the left-hand side of the map (red) showing consistent intensity above and below the QD edge. c, Integrated line profile of the right-hand side of the map (blue) showing an intensity enhancement above and below the QD. The horizontal dashed lines in b and c show the intensity enhancement in the middle QD region and similar intensity in the side region. Error bars in b and c represent standard deviation.
