We propose a new method to align liquid crystals using microgrooves that are fabricated by a stamping process. This rubless alignment method has the advantage of accurate control of the pretilt angle and azimuthal surface anchoring energy by means of changing the surface morphology. In this paper we discuss the contro…

Bi 2 O 3 ‐based cubic solid solutions containing 20% Er 2 O 3 undergo transformation to a rhombohedral phase when annealed at temperatures 635°C. This transformation is generally very sluggish and is accompanied by a decrease in conductivity. The kinetics of this transformation were enhanced by the addition of CaO and…
