Abstract
(S1) Thin PEI film characterizations such as thickness, surface morphology and deposited layer profile. (S2) Differential resonant extinction contour plots as functions of hBN damping and ribbon geometry. (S3) Sensing of bare hBN nanoribbons with varying CO2 concentration. (S4) Fit of PEI permittivity model from experimental transmission spectrum as a function of CO2 concentration. (S5) Simulated response of different hBN ribbon geometry in varying CO2 concentration. (S6) Sensing of hBN nanoribbons and 30 nm PEI coating with varying CO2 concentration.
