Table 2 Thicknesses d of a homogeneous DiMethoxyethyl-PTCDI film below the surface roughness and the corresponding roughness layer heights d r determined for a film with the use of different roughness profiles
Roughness profile of | d/nm | dr/nm |
|---|---|---|
DiMethoxyethyl-PTCDI (AFM) | 0 | 107.6 ± 0.3 |
DiPhenyl-PTCDI (AFM) | 0 | 104.2 ± 0.3 |
Proposed model with σ = 13.5% | 0 | 94.8 ± 0.3 |
50:50 model | 27 ± 76 | 39 ± 70 |
