铁电材料的特征在于可由外加场切换的自发极化，其可充当“门”来控制铁电/绝缘体界面的各种性质。本文综述了近年来铁电极化对氧化物异质/同质界面调制的研究进展。我们讨论了最近开发的四维扫描透射电子显微镜的潜在应用，以及它如何能够提供铁电极化诱导现象的基本理解的见解，并刺激未来的计算研究。最后，我们展望了材料计算对该领域未来发展的潜力、挑战和机遇。
Ferroelectric materials are characterized by the spontaneous polarization switchable by the applied fields, which can act as a “gate” to control various properties of ferroelectric/insulator interfaces. Here we review the recent studies on the modulation of oxide hetero-/homo-interfaces by ferroelectric polarization. We discuss the potential applications of recently developed four-dimensional scanning transmission electron microscopy and how it can provide insights into the fundamental understanding of ferroelectric polarization-induced phenomena and stimulate future computational studies. Finally, we give the outlook for the potentials, the challenges, and the opportunities for the contribution of materials computation to future progress in the area.
