(a) AFM image of L-Ala film on SiO2, whose film thickness was 50 nm. (b) Tentative normalized absorption spectrum of L-Ala/SS under condition (III) (red line) and reported spectrum of L-Ala (black line) (Kamohara et al., 2008). (c) Effective thickness of L-Ala/SS calculated from reported absorption coefficient as a function of wavelength. |
