Strain-engineering Mott-insulating La2CuO4
Abstract The transition temperature T c of unconventional superconductivity is often tunable. For a monolayer of FeSe, for example, the sweet spot is uniquely bound to titanium-oxide substrates. By contrast for La 2−x Sr x CuO 4 thin films, such substrates are sub-optimal and the highest T c is instead …
