Photocathode Quantum Efficiency of Ultra-Thin Cs2Te Layers On Nb Substrates
Zikri Yusof, Adam Denchfield, Mark Warren +4
The quantum efficiencies (QE) of photocathodes consisting of bulk Nb substrates coated with thin films of Cs2Te are reported. Using the standard recipe for Cs2Te deposition develop…
Evidence for superconductivity at 190 K in a pressure-overdoped cuprate
Alexander C. Mark, Huu T. Do, David Rodriguez +7
It is well established that the critical temperature () of cuprate superconductors can be tuned by pressure. For example, compression decouples the hole doping from chemical d…
Correlation Effects on Coupled Electronic and Structural Properties of Doped Rare-Earth Trihydrides
Adam Denchfield, Hyeondeok Shin, Panchapakesan Ganesh +2
Rare-earth trihydrides (H) exhibit intriguing coupled electronic and structural properties as a function of doping, hydrogen vacancies, and thermodynamic conditions. Theoret…
Quantum Stabilization and Flat Hydrogen-based Bands of Nitrogen-doped Lutetium Hydride
Adam Denchfield, Francesco Belli, Eva Zurek +2
We explore electronic and structural properties of Fmm Lu-H-N structures with specific N,H ordering as plausible candidates for near-ambient superconductivity possibl…
Novel Electronic Structure of Nitrogen-Doped Lutetium Hydrides
Adam Denchfield, Hyowon Park, Russell J. Hemley
First-principles density functional theory (DFT) calculations of Lu-H-N compounds reveal low-energy configurations of Fmm LuHN structures that exhibit…
Designing Quaternary Hydrides with Potential High T Superconductivity
Adam Denchfield, Hyowon Park, Russell J Hemley
While hydrogen-rich materials have been demonstrated to exhibit high T superconductivity at high pressures, there is an ongoing search for ternary and quaternary hydrides that…
