a–b, In-phase (a) and out-of-phase (b) signals (in volts, V) obtained from an 8-layer MoSe2 sample at different pump fluences. c–d, Normalized profiles, whose nearly identical shapes confirm that we are operating in the linear regime and that the transient reflectivity profile is a suitable indicator of the lattice temperature profile. e–f, In-phase (e) and out-of-phase (f) signals (in volts, V) obtained from a 3-layer MoSe2 sample at different probe fluences. g–h, Normalized profiles, whose nearly identical shapes indicate that there are no undesired effects of our probe light on the spatial profiles.
