Hidden lattice instabilities as origin of the conductive interface between insulating LaAlO3 and SrTiO3

Hidden lattice instabilities as origin of the conductive interface between insulating LaAlO3 and SrTiO3

The origin of interfacial conductivity between two insulating oxides, LaAlO3 and SrTiO3, remains elusive despite a long time research. Here, Lee et al. report atomic-scale observation of electron-gas formation for screening hidden ferroelectric-like lattice instabilities, discounting the role of pol...
