Our collaborative paper on La2Ti2O7 thin films led by Dr. Tiffany Kaspar at Pacific Northwest National Lab has been published in Scientific Reports. In this work, we explore the ordering of oxygen interstitial ions to form the layered perovskite-related structure and study its ferroelectric and piezoelectric properties. These materials are exceptionally challenging to synthesize but have exciting properties due to the high ferroelectric Curie temperature that they possess. Nice work Tiffany!
