Research Abstract

I found that the surface relief pattern induced by a single light spot having only a longitudinal electric field (Ez) was strongly dependent on the film thickness. Such a film thickness dependence was not observed in the case of a lateral electric field (Ex, y). I have also succeeded in inducing polymer nanomovement of an azo polymer film by combining metal tip enhancement and radial polarization. I found that the induced surface relief was dependent on the tip force which exerted on the polymer surface. It is considered that adsorption force between the tip end and the polymer surface plays an important role.
