## Abstract When insulator LaAlO~3~ is grown by epitaxy onto a TiO~2~‐terminated {100} surface of insulator SrTiO~3~, the system obtained has a metallic character. This phenomenon has been associated with an electrostatic frustration at the interface, as {100} surfaces of SrTiO~3~ are neutral while

## Abstract Polar interfaces, if abrupt, theoretically create diverging electro‐static potentials. In practice, atomic or electronic reconstructions occur. In the case of the polar (001) interface between the insula‐tors LaAlO~3~ and SrTiO~3~ pictured here, such reconstructions may be the origin of
