PERSPECTIVE: Emergent phases in rare earth nickelate heterostructures

J. Chakhalian, S. Middey

摘要:

通过轨道工程预测LaNiO $_3$层中的高$T_c$超导性在过去十五年中已经引起了广泛的研究努力。在此期间,大量的基于具有钙钛矿结构的稀土镍酸盐家族的薄膜和异质结构被合成和探索。在这个简短的角度来看,我们简要地回顾了散装$RE$ NiO $_3$的复杂性,突出了几个最近的研究结果,在异质结构包含$RE$ NiO $_3$和另一种过渡金属氧化物之间的界面的新兴现象。最后,我们概述了潜在的有趣的未来方向与时域动力学利用新的莫特和拓扑相的人工结构的$RE$ NiO $_3$。

英文摘要:

The prediction of high $T_c$ superconductivity in layers of LaNiO$_3$ through orbital engineering has led to extensive research efforts over the last fifteen years. During this period, a plethora of thin films and heterostructures based rare-earth nickelate family with perovskite structure has been synthesized and explored. In this short perspective, we briefly review the complexity of bulk $RE$NiO$_3$, spotlighting several recent findings of emergent phenomena in heterostructures containing the interface between $RE$NiO$_3$ and another transition metal oxide. Finally, we outline potentially interesting future directions linked to time-domain dynamics to harness new Mott and topological phases in artificial structures of $RE$NiO$_3$.
