Self-Organized Tailoring of Faceted Glass Nanowrinkles for Organic Nanoelectronics

Self-organized wrinkled templates are homogeneously fabricated over a large area (cm2) glass substrates by defocused ion beam irradiation, demonstrating the capability to induce and modify at will out-of-plane tilt of nanofacets with selected slope. We identify region morphological instability which leads faceting for incidence angles respect surface, θ, in range 15° ≤ θ 45°, while normal incidence, = 0°, grazing about 55–60° flat morphology is achieved. The crucial parameter controls slope sawtooth profile local angle on facets corresponds maximum erosion velocity. For 30°, improved lateral order found can be exploited anisotropic confinement functional layers. Here, we highlight role 1D nanopatterned template driving crystallization spun-cast conductive polymer thin films registry faceted nanogrooves. In response, electrical transport properties film achieved overall improvement higher than 60% reference, thus showing potential such transparent large-area nanoelectronics, optoelectronics, biosensing.
