Surface-relief gratings applications

The first investigated azo-polysiloxane contains nucleobases in the side chain. This azo-polymer class presents a potential interest in the fields of optoelectronic or biomolecnle immobilization and nanomanipulation. The optoelectronic applications are the consequence of the azo-materials capacity to generate surface relief grating (SRG) under UV irradiation. In spite of the fact that the SRG problem is stndied by many research gronps, nntil now, the mechanism of the surface...
