Fabrication and characterization of La₂RNi₂O₃/YBa₂Cu₃O_x bilayer thin films (R = La, Pr, Sm)

For quantum materials, the combination of two distinct compounds sometimes leads to emergent properties and opens a new research topic. One of the examples is YBa₂Cu₃O_x/La_1-xCa_xMO₃ bilayers. We would apply this paradigm to the newly discovered superconductor La₂RNi₂O₃ (R = La, Pr, Sm). Bilayers of YBa₂Cu₃O_x/ La₂RNi₂O₃ will be fabricated by PLD and characterized. The main focus will be whether the proximity effect exists. Especially, the change of the carrier concertation in both layers and the signature of the density waves will be discussed.
