Yttrium Superhydrides Revisited: Advanced Experimental and Theoretical Studies of YH, YH and YH
Dmitrii V. Semenok, Pedro N. Ferreira, Di Zhou +10
Yttrium polyhydrides are benchmark materials in high-pressure superconductivity, yet several key properties of the Y-H system remain insufficiently characterized. Here we combine c…
Stability Analysis of Superconductivity in -LaScH and its Experimental Reproducibility from La-Sc Alloys
Dmitrii V. Semenok, Ivan A. Troyan, Di Zhou +4
In this work, we analyze the feasibility of room-temperature superconductivity in the lanthanum-scandium hydride -LaScH. We demonstrate that the electro…
Superhydrides on the way to ambient pressure: weak localization and persistent X-ray photoconductivity in BaSiH
Dmitrii V. Semenok, Di Zhou, Sven Luther +15
Reducing the stabilization pressure of superhydrides represents one of the most important challenges in hydrogen-saturated compound chemistry. Moving in this direction, we studied…
Stability and Superconductivity of Ternary Polyhydrides
Dmitrii V. Semenok, Di Zhou, Wuhao Chen +8
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloy…
Soft superconductivity in covalent bismuth dihydride BiH under extreme conditions
Jianning Guo, Dmitrii V. Semenok, Ivan A. Troyan +14
Strong magnetic fields provide a unique environment for investigating the fundamental properties of superconducting materials, especially for hydride superconductors with large upp…
Transmission of radio-frequency waves and nuclear magnetic resonance in lanthanum superhydrides
Dmitrii V. Semenok, Florian Bärtl, Di Zhou +6
The discovery of near-room temperature superconductivity in the lanthanum hydride LaH has revolutionized this field of research. However, the need to use diamond anvils for…
