Electronic conductivity and structural distortion at the interface between insulators SrTiO3 and LaAlO3

J. -L. Maurice, C. Carretero, M. -J. Casanove +4

When insulator LaAlO3 is grown by epitaxy onto a TiO2-terminated {100} surface of insulator SrTiO3, the resulting system has a metallic character. This phenomenon has been associat…
