Abstract

Domain inverted structures in LiNbO3 (LN) and LiTaO3 (LT) are fabricated by proton exchange followed by rapid heat treatment. The formation and development of the effects of pyroelectric field on domain inversion are investigated. The proton and lithium profiles are measured by SIMS. The Curie temperature of the proton exchanged LT is evaluated by DSC. An internal electric field model is proposed to explain the domain inversion mechanism.
