Baumberger, and W. Meevasana We demonstrate the formation of a two-dimensional electron gas (2DEG) at the (100) surface of the 5 d transition-metal oxide KTaO 3 . From angle-resolved photoemission, we find that quantum confinement lifts the orbital degeneracy of the bulk band structure and leads to a 2DEG composed of ladders of su... [Phys. Rev.
