Supertetragonal BaSnO3 induced giant ferroelectricity in SrTiO3/BaSnO3 superlattices

Jing Li, Qing Zhang, Karin M. Rabe +1

Perovskite BaSnO3 has an Sn s-orbital conduction band minimum, which makes it of interest as a transparent-conducting oxide parent compound but also contraindicates the ferroelectr…
