Microstructural Evolution of Charged Defects in the Fatigue Process of Polycrystalline BiFeO3 Thin Films

Qingqing Ke, Amit Kumar, Xiaojie Lou +4

Fatigue failure in ferroelectrics has been intensively investigated in the past few decades. Most of the mechanisms discussed for ferroelectric fatigue have been built on the "hypo…

Unit cell determination of epitaxial thin films based on reciprocal space vectors by high-resolution X-ray diffractometry

Ping Yang, Huajun Liu, Zuhuang Chen +2

A new approach, based on reciprocal space vectors (RSVs), is developed to determine Bravais lattice types and accurate lattice parameters of epitaxial thin films by high-resolution…

Origin of the Enhanced Polarization in La and Mg Co-substituted BiFeO3 Thin Film during the Fatigue Process

Qingqing Ke, Amit Kumar, Xiaojie Lou +2

We have studied the polarization fatigue of La and Mg co-substituted BiFeO3 thin film, where a polarization peak is observed during the fatigue process. The origin of such anomalou…
