Oriented growth of Te on tgs cleavage faces

Abstract
Ferroelectric domains on TGS cleavage faces can be decorated by well conducting Te layers of more than 100 A thickness. The Te crystallites are large (up to 200 μm) on positive domains and small (∼ 1 μm) on negative domains. On both domains the c-axis of the Te crystallites is parallel to the TGS surface. In addition a fibre texture of the Te films is observed on negative domains with the c-axis of all Te crystallites parallel to the c-axis of the TGS. The mechanism for the decoration of domains on TGS is discussed.
