Two-dimensional electron systems in perovskite oxide heterostructures: Role of the polarity-induced substitutional defects
Shih-Chieh Lin, Cheng-Tai Kuo, Yu-Cheng Shao +17
The discovery of a two-dimensional electron system (2DES) at the interfaces of perovskite oxides such as LaAlO3 and SrTiO3 has motivated enormous efforts in engineering interfacial…
Probing single unit-cell resolved electronic structure modulations in oxide superlattices with standing-wave photoemission
W. Yang, R. U. Chandrasena, M. Gu +9
Control of structural couplings at the complex-oxide interfaces is a powerful platform for creating new ultrathin layers with electronic and magnetic properties unattainable in the…
Interface properties and built-in potential profile of a LaCrO/SrTiO superlattice determined by standing-wave excited photoemission spectroscopy
Shih-Chieh Lin, Cheng-Tai Kuo, Ryan B. Comes +14
LaCrO (LCO) / SrTiO (STO) heterojunctions are intriguing due to a polar discontinuity along (001), two distinct and controllable interface structures [(LaO)/(TiO)$^…
Depth-resolved resonant inelastic x-ray scattering at a superconductor/half-metallic ferromagnet interface through standing-wave excitation
Cheng-Tai Kuo, Shih-Chieh Lin, Giacomo Ghiringhelli +18
We demonstrate that combining standing-wave (SW) excitation with resonant inelastic x-ray scattering (RIXS) can lead to depth resolution and interface sensitivity for studying orbi…
