Microsecond linear optical response in the unusual nematic phase of achiral bimesogens
(2011)Some hydrocarbon linked mesogenic dimers are known to exhibit an additional nematic phase (N(x)) below a conventional uniaxial nematic (N(u)) phase. Although composed of non-chiral molecules, the N(x) phase is found to ... -
Molecular model of biaxial ordering in nematic liquid crystals composed of flat molecules with four mesogenic groups
(2010)Relative stability of uniaxial and biaxial nematic phases is analyzed in a model nematic liquid crystal composed of flat molecules of C-2h symmetry with four mesogenic groups rigidly linked to the same center. The generalized ... -
Optical characteristics of ordinary and tunable 1D Si photonic crystals in the mid-infrared range
(2005)Reflection spectra and photonic band gaps (PBGs) for periodic structures consisting of grooved Si infiltrated with nematic liquid crystals (LCs) E7 have been obtained experimentally and by simulation. Periodically grooved ...
