Table 1. Percentage of Average Orientation of PSI Depending on the Different Directing SAMsa.
| directing SAM | up (%) | down (%) | sideways (%) | coverage (PSI trimer/μm2) |
|---|---|---|---|---|
| MPS | 57 | 18 | 25 | 723 |
| 2ME | 11 | 69 | 20 | 853 |
The results were obtained by measuring the asymmetry of the I–V curves by CP-AFM. The average coverage on an area of 1 μm2 was calculated from AFM height images. The table summarizes the statistical distributions of the I–V curves of over 100 points for both director SAMs.
