  • Abstract The electronic structure at interface between two insulators LaAlO3 and SrTiO3 has been investigated by using scanning tunneling microscopy and spectroscopy. The atomic-scale interfacial band structure is also demonstrated in the work with the consideration of the tip-induced band bending effect.
    Experimental results indicate that the magnitude of the built-in field across LaAlO3 is 0.075±0.005 V/Å. The band bending on SrTiO3 side at the heterointerface is observed. The band downshift of SrTiO3 side at the interface is 0.1 eV with ~1 nm decay length.
