a Schematic illustration of single or binary inhibitors suppressing step spreading via step pinning or/and kink blocking. b–e Dependence of step velocity v relative to that in the absence of any inhibitor v0 (v/v0) on CA concentrations in CA/PGA 1:0.17 (b), CA/EA 1:0.007 (c), CA/GaA 1:0.025 (d), and CA/PrA 1:2.73 (e), Solid symbols are the experiment values, and dashed lines are the fits to Eqs. (S22–24). Error bars are the standard deviation from an average of 15–25 measurements of v. f–i The correlation between the theoretical step velocity v relative to that in pure solution v0 and the concentrations of CA and polyphenols (PGA, EA, GaA, PrA) along (001) step plane. Derived values of ξ, KLB, and KLP of a single inhibitor are listed in Supplementary Tables 1–3. The surface area per adsorption site S0 = 0.12 nm2 was estimated from the structure of COM crystals.
