Abstract :
Superlattice thin films are fabricated by the pulsed laser deposition method using LiNbO3 and LiTaO3 as target members. Through our structural and compositional analyses by x-ray diffractometry and field effect scanning transmission electron microscopy with electron dispersive x-ray spectroscopy, these films are found to contain Li-deficient phase, i.e. LiNb3O8 and LiTa3O8..
