Breaking electron pairs in the pseudogap regime of SmTiO${}_3$/SrTiO${}_3$/SmTiO${}_3$ quantum wells

Xinyi Wu, Lu Chen, Jianan Li +5

The strongly correlated two-dimensional electron liquid within SmTiO${}_3$/SrTiO${}_3$/SmTiO${}_3$ quantum well structures exhibits a pseudogap phase when the quantum well width is suffi…
