[HTML][HTML] Searching for superconductivity in high entropy oxide Ruddlesden–Popper cuprate films
In this work, the high entropy oxide A 2 CuO 4 Ruddlesden–Popper (La 0.2 Pr 0.2 Nd 0.2 Sm
0.2 Eu 0.2) 2 CuO 4 is explored by charge doping with Ce+ 4 and Sr+ 2 at concentrations
known to induce superconductivity in the simple parent compounds, Nd 2 CuO 4 and La 2
CuO 4. Electron doped (La 0.185 Pr 0.185 Nd 0.185 Sm 0.185 Eu 0.185 Ce 0.075) 2 CuO 4
and hole doped (La 0.18 Pr 0.18 Nd 0.18 Sm 0.18 Eu 0.18 Sr 0.1) 2 CuO 4 are synthesized
and shown to be single crystal, epitaxially strained, and highly uniform. Transport …
