论文摘要
The effects of atomic-scale disorder and charge (de)localization holds significant importance,and they provide essential insights in unravelling the role that strong and weak correlations play in condensed matter systems.For perovskite oxide heterostructures,while disorders introduced via various external stimuli have strong influences on the (de)localization of the interfacial two-dimensional (2D) electrons, these factors alone could not fully account for the system's charge在这里，我们确定位于LAALO3/SRTIO3（LAO/STO）界面的特定杂交状态中位于特定的杂交状态中的移位2D游离电子的动力学。这项实验研究结合了运输测量和温度依赖性X射线吸收光谱的定位，并表明了2D的定位，并表明了2D的定位。适用于非晶态和结晶界面系统。我们证明，界面杂交在调节2D电子定位效应方面起着关键作用。您的研究解决了2D电子的位置，并强调了Interfiacial Hybridization Consection Consection Internization Internitive Internor Internor Internor Internor Internos in n Internitization in Internization in Internization in Internization in Internization Internitiation cons in Internization Internization Internization in ninterization cons of 2d evers of the的位置。
The effects of atomic-scale disorder and charge (de)localization holds significant importance,and they provide essential insights in unravelling the role that strong and weak correlations play in condensed matter systems.For perovskite oxide heterostructures,while disorders introduced via various external stimuli have strong influences on the (de)localization of the interfacial two-dimensional (2D) electrons, these factors alone could not fully account for the system's charge dynamics where interfacial hybridization holds very strong influence.Here, we determine that the displaced 2D free electrons are localized in the specific hybridized states at the LaAlO3/SrTiO3(LAO/STO) interface.This experimental study combines both transport measurements and temperature-dependent X-ray absorption spectroscopy and suggests the localization of 2D electrons can be induced via temperature reduction or ionic liquid gating and it applies to both amorphous and crystalline interfacial systems.Specifically, we demonstrate that interfacial hybridization plays a pivotal role in regulating the 2D electron localization effects.Our study resolves the location where the 2D electrons are localized and highlights the importance of interfacial hybridization and opens further scientific investigation of its influence on 2D charge localization in oxide heterointerfaces.
