The substrates exhibit high absorption of 785 nm Raman excitation light (>60%) to create large, localized electric field enhancement (~10 4 ), which lead to enhanced Raman scattering.

They utilized single atom Au clusters to intercalate 2H-TaS 2, achieving surface enhanced Raman scattering (SERS) enhancement effect of two orders of magnitude relative to the parent 2H-TaS 2.
