论文摘要
二维(2D)过渡金属氧化物钙钛矿大大扩展了可用的2D多功能材料系统的领域。在这里,基于密度功能理论计算,我们预测了伴随双层中的绝缘体 - 金属相变的存在,$ knbo_ {3} $和$ ktao_ {3} $通过应用应变工程和/或外部电场。我们的结果将有助于几层过渡金属氧化金属钙钛矿在新兴的旋转型和菌株中的应用。
Two-dimensional (2D) transition-metal oxide perovskites greatly expand the field of available 2D multifunctional material systems. Here, based on density functional theory calculations, we predicted the presence of ferromagnetism orders accompanying with an insulator-metal phase transition in bilayer $KNbO_{3}$ and $KTaO_{3}$ by applying strain engineering and/or external electric field. Our results will contribute to the applications of few-layer transition metal oxide perovskites in the emerging spintronics and straintronics.
