Polaron-mediated metal-insulator transition and proton conduction in hydrogenated nickelate perovskites
Hang Ma, Tianxing Ma, Ying Liang
Nickel-based perovskites, owing to their spontaneous hydrogen uptake and the dramatic increase in resistivity upon hydrogenation, have emerged as promising candidates for proton-co…
Role of small-radius and high-electronegativity A-Site dopants in enhancing proton transport and stability of perovskite electrolytes
Hang Ma, Ying Liang, Tianxing Ma
The paper uses first‑principles calculations to show that small, highly electronegative A‑site dopants such as Ca improve both proton conductivity and chemical stability in BaCeO₃…
Lattice-Distortion-Mediated Proton Pairing and Trapping in Solid State Oxides
Hang Ma, Jiajun Linghu, Nannan Han +4
Experiments have evidenced proton pairing in Y-doped BaZrO3. However, the nature of proton pairing and its impact on conduction remain insufficiently understood theoretically. Here…
In-depth Investigation of Conduction Mechanism on Defect-induced Proton-conducting Electrolytes BaHfO
Peng Feng, Hang Ma, Kuan Yang +5
This study utilizes first-principles computational methods to comprehensively analyze the impact of A-site doping on the proton conduction properties of BaHfO. The goal is to o…
Hydrogen Bond Strength Dictates the Rate-Limiting Steps of Diffusion in Proton-Conducting Perovskites:A Critical Length Perspective
Hang Ma, Ying Liang, Tianxing Ma +6
Identifying the rate-limiting step of proton migration in proton-conducting oxides is essential for assessing and regulating proton conductivity. Proton migration based on the Grot…
Comparison of superconducting pairing in doped cuprates and nickelates within an extended Hubbard model
Yicheng Xiong, Hang Ma, Hongxing Liu +2
Within a Hubbard model, we investigate the superconducting pairing behavior of infinite-layer nickelate and cuprate superconductors by using the determinant quan…
