Direct imaging of disordered residual oxygen and its impact on electronic structure in an infinite-layer nickelate superlattice
Chao Yang, Hongguang Wang, Roberto A. Ortiz +4
Infinite layer nickelates have garnered significant attention due to their potential for high-temperature superconductivity. Despite extensive research, the interplay between oxyge…
Adsorption-controlled Growth of Homoepitaxial c-plane Sapphire Films
Lena N. Majer, Tolga Acartürk, Peter A. van Aken +13
Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for…
Unraveling nano-scale effects of topotactic reduction in LaNiO crystals
Yu-Mi Wu, Pascal Puphal, Masahiko Isobe +4
Infinite-layer nickelates stand as a promising frontier in the exploration of unconventional superconductivity. Their synthesis through topotactic oxygen reduction from the parent…
Interface Design Beyond Epitaxy: Oxide Heterostructures Comprising Symmetry-forbidden Interfaces
Hongguang Wang, Varun Harbola, Yu-Jung Wu +2
Epitaxial growth of thin-film heterostructures is generally considered the most successful procedure to obtain interfaces of excellent structural and electronic quality between thr…
Topotactically induced oxygen vacancy order in nickelate single crystals
Yu-Mi Wu, Pascal Puphal, Hangoo Lee +6
The strong structure-property coupling in rare-earth nickelates has spurred the realization of new quantum phases in rapid succession. Recently, topotactic transformations have pro…
Employing High-temperature-grown SrZrO Buffer to Enhance the Electron Mobility in La:BaSnO-based Heterostructures
Prosper Ngabonziza, Jisung Park, Wilfried Sigle +3
We report a synthetic route to achieve high electron mobility at room temperature in epitaxial La:BaSnO/SrZrO heterostructures prepared on several oxide substrates. Room-te…
