First-principles study of surface charging in LaAlO sub(3) / SrTiO sub(3) heterostructures

The two-dimensional electron gas (2DEG) observed at the interface between LaAlO sub(3) (LAO) and SrTiO sub(3) (STO) is known to be very sensitive to the proximity of the LaAlO sub(3) surface and the conditions to which the surface is exposed. We use first-principles calculations to study surface rec...
