Fig. 6From: 4-Nitrobenzene Grafted in Porous Silicon: Application to Optical LithographyEvolution from the reflectivity of PSi grafted with 4-NBD by potentiostatic method and immersed in NaOH 0.5 M. The spectra, to ease their comparison, are vertically shifted with respect to each other by a 30 % amount. The bottom spectrum has no vertical shiftBack to article page
