a, Spatial profiles obtained using the hydrodynamic model describing the in-phase (solid line) and out-of-phase (dashed line) components of a monolayer MoSe2 signal (solid circles for in-phase, open circles for out-of-phase). b, Corresponding profiles obtained using the conventional thermoelastic model, which considers thermal expansion and the thermomechanical energy balance, but without including a thermoelastic heat flux contribution. c, Profiles from the combined hydro-thermoelastic model, which provides the best description of the experimental dataset. All profiles are normalized to the peak of the fit of the in-phase signal, and the out-of-phase profiles are multiplied by − 1.
