^aσ_Si: silicon/inner n-decyl layer interface (σ_Si). ρ_e,1, ρ_e,2, and ρ_e,3 are the electron densities of the first, second, and third layers from the Si surface, respectively. h₁, h₂, and h₃ are the thicknesses of the first, second, and third layers from the Si surface, respectively. σ₁, σ₂, and σ₃ are the surface RMS roughnesses of the first, second, and third layers from the Si surface, respectively. Note that ρ_e,2, ρ_e,3, h₂, and h₃ were fixed to the theoretical dimension and electron density of the backbone and side chains derived from the previous report.⁴⁴ Note that the error values of h₁, h₂, and h₃ are ±1.0 Å. The error values of σ_Si, σ₁, σ₂, and σ₃ are ∼10% of the σ values. The error values of ρ_e,1, ρ_e,2, and ρ_e,3 are ∼10% of the ρ_e values.
