Each LDOS corresponds to a AlO2 or TiO2 plane. The black curve corresponds to the total LDOS of the TiO2 plane, the blue, green and red curves correspond respectively to the dxy orbital, the dyz + dxz orbitals of Ti and the 2p states of oxygen. Right panel: Electronic band structure of the STO in LAO/STO system. Inset shows a zoomed-in view of band avoiding and splitting due to the atomic and Rashba spin-orbit coupling.
