Extended Data Fig. 6: Diffraction sensitivity to lattice normal modes.
(a)–(e) Sensitivity of satellite peaks to lattice normal modes for 2° WSe2 /MoSe2. In this context, we define the scattering enhancement F to be the derivative of the peak intensity I with respect to the r.m.s. atomic displacement x of the mode, normalized by the intensity I0 at zero displacement: F ≔ (dI/dx)/I0. The top-five most efficient modes are ranked from most efficient (a) to least efficient (e). (f)–(j) Sensitivity of satellite peaks to lattice normal modes for 57° WSe2/MoSe2. The top-five most efficient modes are ranked from most efficient (f) to least efficient (j).
