Orbital-selective confinement effect of Ru $4d$ orbitals in SrRuO${}_3$ ultrathin film

Soonmin Kang, Yi Tseng, Beom Hyun Kim +11

The electronic structure of SrRuO${}_3$ thin film with thickness from 50 to 1 unit cell (u.c.) is investigated via the resonant inelastic x-ray scattering (RIXS) technique at the O K…
