Fig. 8From: 4-Nitrobenzene Grafted in Porous Silicon: Application to Optical LithographyEvolution from the reflectivity of PSi grafted with eight CV cycles and immersed in NaOH 0.5 M. The spectra, to ease their comparison, are vertically shifted with respect to each other by a 25 % amount. The bottom spectrum has no vertical shiftBack to article page
