The recent discovery of superconductivity in the nickelates provides another angle to investigate this phenomenon in the high-Tc cuprates and hopefully help solve the mechanism of their unconventional superconductivity. Here, the authors report an increase in Tc for Pr0.8Sr0.2NiO2 where strain from the underlying LSAT substrate plays a possible role, supporting simulations also reveal the contributing role Ni and O orbitals hybridisation play in the unconventional pairing.
