Heterostructuring as Gateway to Electron Doping of Nickelate Superconductors
Chao Deng, Motoharu Kitatani, Guiwen Jiang +7
Despite enormous expenditures in the research field, the electron-doped side of nickelate superconductors remains uncharted territory. Substituting the trivalent rare-earth cations…
Beyond the conventional Emery model: crucial role of long-range hopping for cuprate superconductivity
Eric Jacob, M. O. Malcolms, Viktor Christiansson +6
The Emery model is the quintessential model for cuprate superconductors. In his eponymous paper, Emery only considered the next-nearest-neighbor oxygen-copper hopping. Later, also…
Substrate and cation engineering for optimizing superconductivity in infinite-layer nickelates
Viktor Christiansson, Karsten Held
In a recent experiment [Nature 642, 58 (2025)], a new record for the superconducting critical temperature among infinite-layer nickelates has been reported in doped SmNiO…
Surfaces and interfaces of infinite-layer nickelates studied by dynamical mean-field theory
Leonard M. Verhoff, Liang Si, Karsten Held
Infinite-layer nickelate superconductors are typically synthesized as thin films and thus include, besides the more bulk-like inner layers, distinct surface and interface layers in…
Lattice dynamics of the infinite-layer nickelate LaNiO
Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8
Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
Topotactical Hydrogen Induced Single-Band -wave Superconductivity in LaNiO
Ying Gao, Wenfeng Wu, Zhaoxin Liu +2
LaNiO is an antiferromagnetic insulator with a structural resemblance to its cuprate counterpart, LaCuO. However, LaCuO has a Cu or 3 electronic…
