Permanent grayscales in a π bistable twisted nematic liquid crystal display have been demonstrated. This display can be switched between –22.5° and 157.5° twist states by means of a combination of strong in-plane electric fields and vertical electric field for creating both the planar anchoring breaking and an electrohydrodynamic flow. The switching of the twist states during the Frederiks tran...

From the point of view of biocompatibility of bone analog materials, cell-material interaction is of fundamental importance. In this article, we report the effect of pulse electric field stimulation on cell-material interaction by analyzing cellular functionality and viability. An in-house fabricated pulse electric field setup was used for the application of electric field during cell culture e...

The spin field-effect transistor envisioned by Datta and Das opens a gateway to spin information processing. Although the coherent manipulation of electron spins in semiconductors is now possible, the realization of a functional spin field-effect transistor for information processing has yet to be achieved, owing to several fundamental challenges such as the low spin-injection efficiency due to...

In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...

In this talk, we discuss several topics related to the Abelian-projected SU(3)-QCD. First of them is the Aharonov-Bohm effect emerging during the extension of this theory by the introduction of the Θ-term. Another topic is devoted to various consequences of screening of the dual vector bosons by electric vortex loops. In particular, it is demonstrated that this effect modifies significantly the...

The classical Yang-Mills equation of motion is numerically investigated in the Lorentz gauge for a SU(2) gauge group. The color-electric field of two point-like charges is studied in the " empty " vacuum and in a state with an instanton present. We found that the color-electric field lines are expelled from the instanton region giving rise to a dual Meissner effect. The origin of this effect is...

A molecular dynamic (MD) modeling approach was applied to evaluate the effect of external electric field on gliadin protein structure and surface properties. Static electric field strengths of 0.001 V/nm and 0.002 V/nm induced conformational changes in the protein but had no significant effect on its surface properties. The study of hydrogen bond evolution during the course of simulation reveal...

Epitaxial multilayers, consisting of a PrBa2Cu307_ x buffer layer, ultrathin YBa2Cu307_ x and SrTiO 3, have been grown for application in electric field effect devices. Different analytical techniques indicate a sharp interface between the layers and good dielectric properties of the SrTiO3-1ayer. First measurements show clear modification of the superconductor's current-voltage characteristics...

Nonlinear Hall effect in an AC electric field and related phenomena. Abstract It has been shown that in metals and semiconductors the joint action of permanent magnetic and AC electric fields leads to arising of DC surface electric current. The physical reason for such a current is due to essentially non-linear dynamics of electronic gas in the surface layer. In adiabatic limit the analytical e...

Gate-modulated low-temperature Raman spectra reveal that the electric field effect (EFE), pervasive in contemporary electronics, has marked impacts on long-wavelength optical phonons of graphene. The EFE in this two-dimensional honeycomb lattice of carbon atoms creates large density modulations of carriers with linear dispersion (known as Dirac fermions). Our EFE Raman spectra display the inter...
