Light tuning of selective Bragg diffraction of the oblique helicoidal cholesteric
Igor Gvozdovskyy, Halyna Bogatyryova, Natalia Kasian +2
It is known that the oblique helicoidal cholesteric structure (Ch), which is formed in alternating electrical field applied to the chiral nematic phase (N*) at temperatures…
Induced smectic ordering and blue phase formation in mixtures of cyanobiphenyls and cholesterol esters
Natalia A. Kasian, Longin N. Lisetski, Serhii E. Ivanchenko +3
It has been found that in mixtures of nematic E7 and smectogenic cholesteryl oleyl carbonate (COC) the S-N* transition temperature is substantially (by ~20 K) increased, as com…
Bragg diffraction of higher orders on oblique helicoidal liquid crystal structures
H. Bogatyryova, V. Chornous, L. Lisetski +1
For the oblique helicoidal structure of the chiral twist-bend nematic-forming mixture of CB7CB/CB6OCB/5CB doped by light-sensitive chiral compound based on azo-fragment, two conseq…
