Resonant soft X-ray scattering study of fluidic phases with no electron density modulation

ORAL

Abstract

We have demonstrated that, when operated at carbon K-edge, the linearly polarized soft X-rays can enable bond orientation sensitivity, which can be utilized to probe the otherwise forbidden peak from the helices of twist bend nematic [2], B4 helical nanofilament phase [1], and cholesterol phase. Here we show that the same principle can be used to probe blue phase [3]. Furthermore, we discuss the relationship between the incoming linearly polarized X-rays, and the anisotropy in the scattering pattern. Future direction will be discussed as well [1] C. Zhu, et al.
