Lithographically patterned substrates were used as templates of optical scatterers that seeded the inorganic phototropic growth of Se–Te. Relative to films grown on nominally featureless substrates, films grown on substrates having patterned optica
Plants exhibit phototropism in which growth is directed toward sunlight and demonstrate morphological plasticity in response to changes in the spectral distribution of the incident illumination. Inorganic phototropic growth via template-free, light-d

We describe herein a path-dependent “history” effect wherein the film morphology generated in the second step of a two-step inorganic phototropic growth process depends on a preexisting structure that has been first grown under different optical
