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)$^…
Electronic structure of negative charge transfer CaFeO3 across the metal-insulator transition
Paul C. Rogge, Ravini U. Chandrasena, Antonio Cammarata +12
We investigated the metal-insulator transition for epitaxial thin films of the perovskite CaFeO3, a material with a significant oxygen ligand hole contribution to its electronic st…
Element- and momentum-resolved electronic structure of the dilute magnetic semiconductor manganese doped gallium arsenide
Slavomír Nemšák, Mathias Gehlmann, Cheng-Tai Kuo +10
The dilute magnetic semiconductors have promise in spin-based electronics applications due to their potential for ferromagnetic order at room temperature, and various unique switch…
