Investigations on Electrooptical Effects in Chiral Discotic Columnar Mesophases
Investigations on the nature of both linear and nonlinear electrooptic eeects in columnar mesophases of chiral discotic dibenzopy-rene and triphenylene derivatives and their mixtures are presented. We specially focus on the innuence of chirality on the switching process. INTRODUCTION Ferroelectricity in tilted smectic phases of chiral molecules was predicted to occur by R. B. Meyer et al. in 19...
متن کاملEffects of Aluminum, Silicon And Ferro Silicon Anti Oxidants in MgO C Refractories
Three different materials (aluminum, ferro -silicon and silicon) were used as antioxidants in order to prevent the decarburization process and to keep and/or increase the final properties in MgO-C refractories. Their effects were compared by measuring the physical and mechanical properties as well as oxidation and the resultant phases and microstructures, in the temperature range of 200-1600 ...
متن کاملDetectivity enhancement in THz electrooptical sampling.
We demonstrate and discuss a simple scheme that significantly enhances the detectivity of THz electro-optical sampling by introducing a sequence of Brewster windows that increases the ellipticity of the probe beam. By varying the window material or the number of Brewster windows, the enhancement factor can be adjusted; we demonstrate an enhancement factor of ≈20 with four ZnSe Brewster windows....
متن کاملRadiation Effects in Silicon
Any silicon device that has left the manufacturing process and goes into an application will be exposed to some degree of high-energy electromagnetic or particle radiation. Most devices, however, have seen the highest degree of exposure to particle irradiation already during the manufacturing process, the most common irradiation process being ion implantation. Less common is the exposure of sil...
متن کاملSimple electrooptical sensors for inorganic anions.
[reaction: see text] Electrooptical sensors consisting of a conjugated chromophore undergoing a change in color and a redox-active moiety such as quinone fused to the chromophore were synthesized. Strong changes in colorimetric and electrochemical properties were observed in the presence of inorganic anions. A unique anion-specific response was observed for fluoride, pyrophosphate, and acetate....
