## Description

- description: Thermally-induced surface reconstruction of α-Al2O3 was used to fabricate
    corrugated templates of different periods to support percolated ultrathin metal
    film. Reflectance analysis and simulations revealed the coupling of a hybrid NIR-SPP
    mode along its corrugation vector (k_corrugation). The fabricated samples enhanced
    Raman signals of phenyl thiolates (PT) with reduced photo-induced disadvantages
    at λexc = 785 nm. Polarized SERS were performed to study adsorbed molecule–polariton
    interaction on these corrugated thin film surfaces. A twofold SERS anisotropy
    with a cos2(σ) dependency (σ = azimuthal angle) was observed. SERS dichroism of
    PT Raman modes of different polarizability tensors were analysed. A more pronounced
    dependence on corrugation period was observed for totally symmetric a1 modes than
    the non-totally symmetric b1 and b2 modes. Apart from the relative SERS intensity,
    their SERS dichroism was determined mostly by the excitation of SPP along the
    k_corrugation rather than the orientation of PT on sample surface. Edge-on orientation
    of adsorbed PT was predicted due to the absence of a2 modes with both tensor components
    parallel to the surface. Shorter corrugation periods fabricated were reproducible
    and ample for uniform, large-area sensing due to effective SPP coupling at σ =
    0° resulting in a spatially extended SERS excitation volume.
