“…As mentioned above, the surface characterization of atomically controlled SrTiO 3 surfaces and their functionality at the interface have been the focus of the SrTiO 3 research. 14–19 SrTiO 3 , having an ABO 3 type perovskite structure, can have two different surface terminations, which can be prepared by various surface preparation methods. Both chemical etching in buffered hydrofluoric acid (BHF) solution and processes of Ar + sputtering followed by annealing under ultra-high vacuum (UHV) are well-known methods to produce a TiO 2 -terminated SrTiO 3 surface.…”

Polar discontinuities occur in oxide heterostructures due to varying net charges in the sub-unit cell layers. These polar discontinuities lead to structural reconstruction and often create diverse functionalities. This work constructs polar discontinuous in La0.67Sr0.33MnO3/SrCuO2 (LSMO/SCO) heterostructures on a (001)-orientated SrTiO3 (STO) substrate under different configurations. By changing the growth order of LSMO and SCO, we found two different compensating mechanisms for polar discontinuity. When LSMO is grown on SCO, interfacial polarity discontinuities result in the generation of a large number of oxygen vacancies within the LSMO film. Thus, the LSMO magnetism deteriorates. For the SCO/LSMO/SCO trilayer, the SCO capping layer can recover the LSMO magnetism. The scanning transmission electron microscope results show an atomic reconstruction at the SCO-on-LSMO interface and several oxygen vacancies at the SrO sublayer. The interface reconfiguration releases the polar energy, thereby inhibiting the generation of oxygen vacancies and improving the ferromagnetism of the LSMO film. Our work studies the impact of polar discontinuity at the interface, providing insights into the effects of interface polar discontinuities on functional materials.
