LaAlO3/SrTiO3界面导电性的近场成像
Near-field imaging of the LaAlO3/SrTiO3 interfacial conductivity
摘要
Abstract
The LaAlO3/SrTiO3 heterointerface has been discovered to show two-dimensional interfacial conductivity and other intriguing emergent phenomena.Its interfacial conductivity was mainly characterized by electric methods previously.Here the authors present for the first time that scattering-type scanning near-field optical microscopy (s-SNOM) can be employed to spatially image the conductivity of the buried LaAlO3/SrTiO3 interface,providing a new means to study the physics of transition metal oxide heterointerface systems.关键词
