Structure of crystal twins in a cholesteric blue phase I

Liquid crystalline cholesteric blue phases (BPs) attract interest for their fast response times and quasi-polarization-independent phase modulation capabilities. BPs possess a three-dimensional cubic structure and typically form polydomain textures when filled in conventional sandwich cells. Here, w...

Summary:Liquid crystalline cholesteric blue phases (BPs) attract interest for their fast response times and quasi-polarization-independent phase modulation capabilities. BPs possess a three-dimensional cubic structure and typically form polydomain textures when filled in conventional sandwich cells. Here, we have found that the texture of BPs that appears random is in fact composed of crystallographic twins. Results of detailed polarized optical microscopy are presented to provide an insight into the structure of the twin. Our finding shows that crystal twinning, conventionally observed in atomic crystals, can also occur in a fluid crystal with a much larger lattice constant.
