We develop a multifunctional metasurface platform that leverages the combination of loss-engineered substoichiometric titanium oxide (TiO₂-x) and the emerging physical concept of optical bound states in the continuum (BICs) to boost photoinduced charge transfer (PICT) and provide broad spectral tunability, making this semiconductor metasurface not only a competitive platform for surface photocatalytic investigations, but also a promising candidate for boosting sensitivities in in semiconductor-based surface-enhanced Raman scattering (SERS) applications.
