## Description

- description: Over the past decade, Resonant Inelastic X-ray Scattering (RIXS) has
    become an indispensable experimental probe of quantum materials, as energy- and
    momentum-dependent RIXS data on electronic excitations provide unique insight
    into the strength and spatial range of electronic interactions. However, one of
    the most rapidly advancing frontiers in this field – two-dimensional (2D) materials
    and van-der-Waals heterostruc- tures – has thus far not benefited significantly
    from RIXS, because the atomic-scale thickness and micron-scale lateral dimensions
    of typi- cal exfoliated sheets impose severe restrictions on the signal intensity.
    Here we present Ru L3-edge RIXS measurements of spin-orbit and crystal-field excitations
    in nanoflakes of the Kitaev spin-liquid candidate RuCl3. Whereas the data on thick
    flakes are identical to bulk mea- surements, we observe a pronounced red-shift
    and broadening of the crystal-field excitations in flakes with thickness below
    about 7 nm. In contrast, the spin-orbit excitations are independent of thickness.
    Aided by model calculations, we attribute these effects to lattice distortions
    near the surface. Our study paves the way towards RIXS investigations of electronic
    excitations in various other 2D materials and heterostructures.
