Strain-induced tuning of the electronic coulomb interaction in 3d transition metal oxide perovskites

Answer 1

Epitaxial strain offers an effective route to tune the physical parameters in transition metal

oxides. So far, most studies have focused on the effects of strain on the bandwidths and

crystal field splitting, but recent experimental and theoretical works have shown that also the

effective Coulomb interaction changes upon structural modifications. This effect is expected

to be of paramount importance in current material engineering studies based on epitaxy-

based material synthesization. Here, we perform constrained random phase approximation …
