Dynamic control of octahedral rotation in perovskites by defect engineering
Jiahui Jia, Xu He, Arsalan Akhtar +2
Engineering oxygen octahedra rotation patterns in perovskites is a powerful route to design functional materials. Here we propose a strategy that exploits point defects tha…
Non-collinear and strongly asymmetric polar moments at back-gated SrTiO3 interfaces
Fryderyk Lyzwa, Yurii G. Pashkevich, Premysl Marsik +15
The highly mobile electrons at the interface of SrTiO3 with other oxide insulators, such as LaAlO3 or AlOx, are of great current interest. A vertical gate voltage allows controllin…
Giant topological Hall effect in correlated oxide thin films
Lorenzo Vistoli, Wenbo Wang, Anke Sander +15
Strong electronic correlations can produce remarkable phenomena such as metal-insulator transitions and greatly enhance superconductivity, thermoelectricity, or optical non-lineari…
Multiple strain-induced phase transitions in LaNiO3 thin films
M. C. Weber, M. Guennou, N. Dix +9
Strain effects on epitaxial thin films of LaNiO3 grown on different single crystalline substrates are studied by Raman scattering and first-principles simulation. New Raman modes,…
Conducting interfaces between amorphous oxide layers and SrTiO3(110) and SrTiO3(111)
Mateusz Scigaj, Jaume Gazquez, Maria Varela +3
Interfaces between (110) and (111)SrTiO3 (STO) single crystalline substrates and amorphous oxide layers, LaAlO3 (a-LAO), Y:ZrO2 (a-YSZ), and SrTiO3 (a-STO) become conducting above…
Laterally-confined two-dimensional electron gases in self-patterned LaAlO3/SrTiO3 interfaces
M. Foerster, R. Bachelet, V. Laukhin +3
A bottom-up process has been used to engineer the LaAlO3/SrTiO3 interface atomic composition and locally confine the two-dimensional electron gas to lateral sizes in the order of 1…
X-ray interference effects on the determination of structural data in ultrathin La2/3Sr1/3MnO3 epitaxial thin films
D. Pesquera, R. Bachelet, G. Herranz +3
We analyze X-ray diffraction data used to extract cell parameters of ultrathin films on closely matching substrates. We focus on epitaxial La2/3Sr1/3MnO3 films grown on (001) SrTiO…
High mobility conduction at (110) and (111) LaAlO3/SrTiO3 interfaces
Gervasi Herranz, Florencio Sánchez, Nico Dix +2
In recent years, striking discoveries have revealed that two-dimensional electron liquids (2DEL) confined at the interface between oxide band-insulators can be engineered to displa…
Unveiling a two-dimensional electron gas with universal subbands at the surface of SrTiO3
A. F. Santander-Syro, O. Copie, T. Kondo +14
Similar to silicon that is the basis of conventional electronics, strontium titanate (SrTiO3) is the bedrock of the emerging field of oxide electronics. SrTiO3 is the preferred tem…
Towards two-dimensional metallic behavior at LaAlO3/SrTiO3 interfaces
