Understanding and controlling the thermal transport at nanoscale is a key ingredient for the development of future nanoelectronical devices. In this study of thin silicon carbide (SiC) membrane we demonstrate the potential of free electron laser extreme ultraviolet (EUV) transient grating (TG) technique as contactless probe for thermoelastic response at length scales of 84 nm, where the Fourier heat diffusion law is no longer valid. The results have revealed that the mechanical behavior of the system can be fully described in the framework of Lamb waves. Moreover, by use of a bidimensional spatial detector to measure the TG signal, a new feature is the observed, time dependence in the emission angle of the transient diffraction, correlated to the transient grating signal intensity.
