## Description

- description: We use picosecond ultrasonic techniques to investigate phonon transport
    in vdW InSe nanolayers and InSe/hBN heterostructures. Coherent acoustic phonons
    are generated and detected in these 2D systems and allow us to probe elastic parameters
    of different layers and their interfaces. In particular, our study of the elastic
    properties of the interface between vdW layers reveals a strong coupling over
    a wide range of frequencies up to 0.1 THz, offering prospects for high-frequency
    electronics and technologies that require control over the charge and phonon transport
    across an interface. In contrast, we reveal a weak coupling between the InSe nanolayers
    and sapphire substrates, relevant in thermoelectrics and sensing applications,
    which can require quasi-suspended layers.
