Freeze-fracture transmission electron microscopy study of the nanoscale structure of the so-called "twist-bend" nematic phase of the cyanobiphenyl (CB) dimer molecule CB(CH2)7CB reveals ...
(a) Vertical edge imaging under positive electric field. Inset: the helical structure is suppressed and FLC molecules rotate to the left side of the core parallel to the substrates. (b) Horizontal ...
