제목 Detailed Analysis of Gyroid and HPL Structures in Diblock Copolymer Thin Films with Synchrotron Grazing Incidence X-ray Scattering
초록 In this study, a grazing incidence X-ray scattering (GIXS) formula was derived for gyroid and HPL structures formed in thin films supported on substrates. We measured two-dimensional (2D) GIXS patterns for gyroid and HPL structures formed in polystyrene-b-polyisoprene (PS-b-PI) diblock copolymer nanometer-scaled thin films supported on silicon substrates, and conducted a quantitative analysis of the obtained 2D GIXS data with the scattering formula. This analysis provided details (lattice parameter, width of the PS phase, positional distortion factor, orientation and orientation distribution) of both the strucures developed in the diblock copolymer thin films that are not easily obtained using conventional techniques. Moreover, we were able to simulate complete and detailed 2D GIXS patterns with the determined structure parameters.
