چکیده

We present a theoretical investigation of the temperature and electric field dependence of nematic liquid crystal wetting layers close to an aligning substrate within a confined system. Using a mesoscopic Q tensor theory coupled to Maxwell’s equations for the electric field, we consider the existence and stability of homogeneous nematic wetting layers close to the substrate. Numerical results are presented showing the phase diagram for the isotropic (paranematic), nematic and wetting layer states. The effect on the isotropicwetting transition, from first order to second order, when an electric field is applied is then investigated.

Hybrid graphene nematic liquid crystal light scattering device.

A hybrid graphene nematic liquid crystal (LC) light scattering device is presented. This device exploits the inherent poly-crystallinity of chemical vapour deposited (CVD) graphene films to induce directional anchoring and formation of LC multi-domains. This thereby enables efficient light scattering without the need for crossed polarisers or separate alignment layers/additives. The hybrid LC d...

Cumulative Birefringence Effects of Nanosecond Laser Pulses in Dye-doped Planar Nematic Liquid Crystal Layers

New cumulative effects in laser-induced birefringence have been observed under 10Hz-pulse-repetition-rate, nanosecond-duration laser irradiation of azo-dye-doped planarnematic liquid crystal layers at incident intensities I ∼ 1–10 MW/cm2. An irradiation geometry with the incident polarization parallel to the nematic director was used. This geometry does not permit a first-order electric field i...

Inversion effect of electrohydrodynamic vortices in the isotropic and anisotropic phase of thin nematic layers with two free surfaces

2014 Thin layers of nematic liquid crystal with two free surfaces show a vortex pattern if they are subjected to an electric field. In this paper, we study a characteristic inversion of the hydrodynamic flow, that occurs if a pulsed electric field is applied. Such an effect is interpreted in terms of the relaxation mechanisms of the layer. J. Physique LETTRES 42 (1981) L-347 L-351 1

Electrohydrodynamic Flow in Nematic Thin Films with Two Free Surfaces

Thin layers of nematic LC with two free surfaces show a peculiar vortex-pattern when subjected to an electric field. In this paper we report some new observations on the vortex motion and we show that the Felici's model of the charge injection from the electrodes cannot account for some experimental results. The lines of a new electrohydrodynamic model are proposed and compared with the experim...

On the Electric Field Induced Stripe Instability Threshold of Twisted Nematic Layers

Most liquid crystal displays make use of the elect roopt ic properties of twisted nematic layers. Both the s tandard twisted nematic displays of 90° twist [1] as well as the recently developed 'supertwist ' displays of more than 180° twist [2] require director fields which depend only on one spatial coordinate, the coordinate z parallel to the layer normal. Director fields which depend on more ...
