Abstract:
We have been exploring ways in which light induced self inscribed (LISI) waveguides can impose constraints on wrinkle patterns when nanocomposite hybrid sol-gel glass films become unstable to perturbations of a certain wavelength, which reflects some length scale in the microscopic system. Periodicity of wavy structures from nano- to micro- to meso- length scales can be generated reproducibly in the presence of microlithographic features created by inscribing guided waves in the photosensitive nanocomposite. Partial wet-etching of network glass films stimulates buckling of the surface whose wave length, orientation and patterning are controlled over large areas by self-inscribed waveguide relief structures. This presentation discusses methods for patterning wrinkle architectures from nanocomposites and provides a qualitative account of wrinkling over several length scales as nonuniform stresses develop in the films.
