Symmetry breaking at the (111) interfaces of SrTiO${}_3$ hosting a 2D-electron system

G. M. De Luca, R. Di Capua, E. Di Gennaro +7

We used x-ray absorption spectroscopy to study the orbital symmetry and the energy band splitting of (111) LaAlO${}_3$/SrTiO${}_3$ and LaAlO${}_3$/EuTiO${}_3$/SrTiO${}_3$ heterostr…
