Nonlinear optical phonon spectroscopy revealing polaronic signatures of the LaAlO(3)/SrTiO(3) interface

We report the direct observation of lattice phonons confined at LaAlO(3)/SrTiO(3) (LAO/STO) interfaces and STO surfaces using the sum-frequency phonon spectroscopy. This interface-specific nonlinear optical technique unveiled phonon modes localized within a few monolayers at the interface, with inhe...
