Studies from Graduate School of Nanoscience and Technology Yield New Information about Physics Research (Cybotactic behavior in the de Vries smectic-A* liquid-crystal structure formed by a silicon-containing molecule)

By a News Reporter-Staff News Editor at Physics Week -- A new study on Physics Research is now available. According to news reporting out of Daejeon, South Korea, by VerticalNews editors, research stated, "We have identified a metastable liquid-crystal (LC) structure in the de Vries smectic-A* phase (de Vries Sm-A*) formed by silicon-containing molecules under certain boundary conditions. The phase transition with the metastable structure was observed in a LC droplet placed on a planar aligned substrate and LCs confined in the groove of a silicon microchannel."

Our news journalists obtained a quote from the research from the Graduate School of Nanoscience and Technology, "During the rapid cooling step, a batonnet structure was generated as an intermediate and metastable state prior to the transition that yielded the thermodynamically stable toric focal conic domains. This distinctive behavior was characterized using depolarized reflection light microscopy and grazing incidence x-ray diffraction techniques. We concluded that the silicon groups in the molecules that formed the de Vries phase induced the formation of layered clusters called cybotactic structures."

According to the news editors, the research concluded: "This observation is relevant to an exploration of the physical properties of cybotactic de Vries phases and gives a hint as to their optoelectronic applications."
