论文摘要
以Laino $ _ {3} $/basno $ _3 $的示例，我们演示了在这些钙钛矿氧化物之间在接口形成的二维电子气体（2DEG）的密度和分布，可以通过ferroelectric官能材料有效地控制。指向界面的Batio $ _3 $层中引起的极化增强了极性不连续性，进而显着增加了2DEG的密度和限制，而相反的极化耗尽了2DEG。我们的预测和分析基于第一原理计算，可以作为设计用于电子设备中的材料组合的指南。
With the example of LaInO$_{3}$/BaSnO$_3$, we demonstrate how both density and distribution of a two-dimensional electron gas (2DEG) formed at the interface between these perovskite oxides, can be efficiently controlled by a ferroelectric functional material. A polarization induced in a BaTiO$_3$ layer pointing toward the interface enhances the polar discontinuity which, in turn, significantly increases the 2DEG density and confinement, while, the opposite polarization depletes the 2DEG. Our predictions and analysis, based on first-principles calculations, can serve as a guide for designing such material combinations to be used in electronic devices.
