Unipolar Electro-Optic Effect In A Nematic Cell, V. G. Nazarenko, R. Klouda, Oleg Lavrentovich

Chemical Physics Publications

We report on a unipolar electro-optic effect in a nematic liquid crystal cell. The cell placed between two polarizers behaves as an "optical diode:" only one polarity of the applied voltage makes the cell transparent. The phenomenon is caused by a double symmetry breaking at the two plates that bound the nematic slab.
