Topographical transition of submicron pillar array of azo molecular glass induced by circularly polarized light

Abstract The well-aligned submicron patterns on surfaces have attracted wide attention from scientific curiosity to practical applications. Understanding their formation and transition is highly desirable for efficient manufacture of the patterns for many usages. Here, we report a unique observation...
