Influence of the flow on the anchoring of nematic liquid crystals on a Langmuir-Blodgett monolayer studied by optical second-harmonic generation
Valentina S. U. Fazio, Lachezar Komitov, Christian Radüge +2
The influence of capillary flow on the alignment of the nematic liquid crystal MBBA on fatty acid Langmuir-Blodgett monolayers was studied by optical second-harmonic generation. Th…
Comparative study of mixed monolayers of a calixarene with a fatty acid and a non-amphiphilic nematic liquid crystal
F. Nannelli, V. S. U. Fazio, Y. Matsuzawa +2
Many nematic liquid crystals (NLCs) lack a polar headgroup and thus are not able to form stable monolayers at the air/water (a/w) interface. A way to obtain monomolecular films of…
Sensitive methods for estimating the anchoring strength of nematic liquid crystals on Langmuir-Blodgett monolayers of fatty acids
Valentina S. U. Fazio, Francesca Nannelli, Lachezar Komitov
The anchoring of the nematic liquid crystal N-(p-methoxybenzylidene)-p-butylaniline (MBBA) on Langmuir-Blodgett monolayers of fatty acids (COOHCH) was studied as a f…
Phase-matched second-harmonic generation in a ferroelectric liquid crystal waveguide
Valentina S. U. Fazio, S. T. Lagerwall, P. Busson +2
True phase-matched second-harmonic generation in a waveguide of crosslinkable ferroelectric liquid crystals is demonstrated. These materials allow the formation of macroscopically…
Nonlinear optical properties of a channel waveguide produced with crosslinkable ferroelectric liquid crystals
Valentina S. U. Fazio, S. T. Lagerwall, V. Zauls +4
A binary mixture of ferroelectric liquid crystals (FLCs) was used for the design of a channel waveguide. The FLCs possess two important functionalities: a chromophore with a high h…
Incorporation of a non-amphiphilic nematic liquid crystal into a host monolayer
Valentina S. U. Fazio, L. Komitov, S. T. Lagerwall +1
Many nematic liquid crystals are not able to form stable monolayers at the air/water interface because of the lack of a polar headgroup. A possible way to obtain a monomolecular fi…
Alignment transition in a nematic liquid crystal due to field-induced breaking of anchoring
Valentina S. U. Fazio, Lachezar Komitov
We report on the alignment transition of a nematic liquid crystal from initially homeotropic to quasi-planar due to field-induced anchoring breaking. The initial homeotropic alignm…
Alignment of nematic liquid crystals on mixed Langmuir-Blodgett mono-layers
V. S. U. Fazio, L. Komitov, S. T. Lagerwall
Mono-layers of stearic and behenic acids and mixtures of them in different proportions, deposited with the Langmuir-Blodgett technique, were used to study the alignment and the ali…
Alignment and alignment dynamics of nematic liquid crystals on Langmuir-Blodgett mono-layers
V. S. U. Fazio, L. Komitov, S. T. Lagerwall
Mono-layers of stearic and behenic acids deposited with the Langmuir-Blodgett technique, were used as aligning films in nematic liquid crystal cells. During the filling process the…
Conversion efficiency in a Josephson effect mixer
Valentina S. U. Fazio
The RCSJ (Resistor-Capacitor Shunted Junction) model provides us an analytical formula for the conversion efficiency for a resonant Josephson effect mixer. An external rf signal is…
