Preparation of KTN Films on Single Crystal Quartz Substrates

摘要

The key to preparingrnhigh-orientation KTNrnfilms on transparentrnquartz is properrncontrol of the densityrnof laser energy and thernannealingrntemperature.rnAt present, the study of KTN is still in experimental stages. It is difficult to prepare simple KTN bulk crystals or good transparent KTN ceramics, which restricts use for its optical characteristics. Its desirable optical properties, however, have prompted rapid development in the study of preparing KTN films.
