Anomalous excitons and screenings unveiling strong electronic correlations in SrTiNbO, 0x0.005
Pranjal Kumar Gogoi, Lorenzo Sponza, Daniel Schmidt +8
Electron-electron (e-e) and electron-hole (e-h) interactions are often associated with many exotic phenomena in correlated electron systems. Here, we report an observation of anoma…
