Controlling Cubicity of PS-b-PMMA Double Gyroid Unit Cell in the Direction Perpendicular to the Substrate: Inducing Reflection Wavelength Difference |
| 초록 |
In this study, we present a facile approach to control cubicity of double gyroid (GYR) unit cell in the direction perpendicular to the substrate using polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) self-assembly. Evaporation-control solvent vapor annealing (ECSVA) was used to control cubicity without any deformation of the structure in lateral direction. PS-b-PMMA GYR with two different cubicity parameter obtained from the ECSVA were transformed to Air-Al2O3 GYR through sequential infiltration synthesis and following treatment with O2 plasma to enhance refractive contrast between the channel and matrix of GYR. With successfully increased refractive contrast which sharpens UV reflectance peak to observe photonics-related property more effectively, GYR having different cubicity exhibits difference in reflection wavelength owing to dimensional contrast of the unit cell in the direction perpendicular to the substrate. |
