Method for producing a single-crystalline film of KLN or KLNT

摘要

A method for producing a single-crystalline film made of a single crystal of lithium potassium niobate-lithium potassium tantalate solid solution or a single crystal of lithium potassium niobate, including the steps of preparing a target made of a material for the single-crystalline film, preparing a foundation made of a single crystal of lithium potassium niobate-lithium potassium tantalate solid solution or a single crystal of lithium potassium niobate, irradiating the target to gasify molecules constituting the target by dissociation and evaporation thereof, and epitaxially growing the single-crystalline film on the foundation.
