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...
