Decoupling carrier concentration and electron-phonon coupling in oxide heterostructures observed with resonant inelastic x-ray scattering

D. Meyers, Ken Nakatsukasa, Sai Mu +19

We report the observation of multiple phonon satellite features in ultra thin superlattices of form $n$SrIrO${}_3$/$m$SrTiO${}_3$ using resonant inelastic x-ray scattering. As the valu…
