Growth and characterization of the La${}_3$Ni${}_2$O${}_{7-\hat{I}´}$ thin films: dominant contribution of the $d_{x^2-y^2}$ orbital at ambient pressure

By using the pulsed-laser-ablation technique, we have successfully grown the La${}_3$Ni${}_2$O${}_{7-\hat{I}´}$ thin films with $c$-axis orientation perpendicular to the film surface. X-ra…
