"cvercomes complex fabrication... BaTiO3 ferroelectric films deposited onto La0.67Sr0.33MnO3 metallic layers using >800℃ pulsed laser deposition resulting in single-domain configuration.,, Sr ions diffused towards interface, creating positively charged surface uniformly aligning polarizations across film... large-scale single-domain film production beyond 5 × 5 mm, possibly through industrial processes like spin coating... enhance neuromorphic computing synapse performance, optoelectronics, catalysis"
