| Research Abstract |
By developing the local resonat X-ray scattering technique using a synchrotron X-ray microbeam, novel sub-phases appearing in the chiral smectic liquid crystals were studies and new information about the inter molecular interaction and the phase transition mechanism has been obtained. A sub-phase with a six-layer periodicity which appeared between the ferroelectric and the antiferroelectric phases was found in the chiral smectic liquid crystal mixture and it agreeed well with the theoretical model. During the electric field induced phase transition, a 12-layer periodicity phase appeared. An x-ray intensity analysis suggested that the molecular configuration realized in this phase was the new intermediate phase between the adjacent phases.
