Journal ArticleDOI
Negligible oxygen vacancies, low critical current density, electric-field modulation, in-plane anisotropic and high-field transport of a superconducting Nd0.8Sr0.2NiO2/SrTiO3 heterostructure
Xiaorong Zhou,Zexin Feng,Peixin Qin,Han Yan,Xiaoning Wang,Pan Nie,Haojiang Wu,Xin Zhang,Hongyu Chen,Ziang Meng,Zengwei Zhu,Zhiqi Liu +11 more
TL;DR: In this article, a 14-nm-thick superconducting Nd0.8Sr0.2NiO2/SrTiO3 thin-film heterostructure with an onset transition temperature of 9.5 K was studied.
Journal ArticleDOI

TL;DR: In this paper, the effect of sublayer thickness on the magnetic structure and exchange coupling at (111)-oriented perovskite oxide interfaces was investigated, and it was shown that the antiferromagnetic (AF) properties of the LSFO sublayers are preserved with an out-of-plane canting of the AF spin axis.
Journal ArticleDOI
Effects of thermal annealing on the band alignment of lanthanum aluminate on silicon investigated by x-ray photoelectron spectroscopy
TL;DR: In this paper, the authors investigate the changes in the band offsets of lanthanum aluminate on silicon after postdeposition annealing at 600 and 800°C by x-ray photoelectron spectroscopy (XPS) and conclude that the band offset changes originate mainly from an interfacial effect.
Journal ArticleDOI
Atomically flat interface between a single-terminated LaAlO3 substrate and SrTiO3 thin film is insulating
Zhiqi Liu,Zhen Huang,W. M. Lü,Kalon Gopinadhan,Xiao Renshaw Wang,Anil Annadi,Thirumalai Venkatesan,Ariando +7 more
TL;DR: In this paper, the surface termination of (100)-oriented LaAlO3 (LAO) single crystals was examined by atomic force microscopy and optimized to produce a single-terminated atomically flat surface by annealing.
Journal ArticleDOI
Parallel charge sheets of electron liquid and gas in La0.5Sr0.5TiO3/SrTiO3 heterostructures.
X. Renshaw Wang,X. Renshaw Wang,Lijun Sun,Zhen Huang,W. M. Lü,Mallikarjuna Rao Motapothula,Anil Annadi,Zhiqi Liu,Shengwei Zeng,Thirumalai Venkatesan,Ariando +10 more
TL;DR: O/STO heterostructures point to new functionalities, in addition to magnetism and superconductivity in STO-based systems, which could be exploited in a multifunctional context.
