- 31 May 2000
We have fabricated a vertically aligned 4-domain nematic liquid crystal display cell with thin film transistor. Unlike the conventional method constructing 4-domain, i.e., protrusion and surrounding… Expand
Growth, Ferroelectric Properties, and Phonon Modes of YMnO3 Single Crystal
YMnO 3 single crystals were grown by flux method and plate-like single crystals with the c-axis perpendicular to the surfaces were obtained. The maximum size of these crystals was about 2 x 2 x 0.07… Expand
