Charge-transfer effect in hard x-ray 1 and 2 photoemission spectra: LDA+DMFT and cluster-model analysis
Mahnaz Ghiasi, Atsushi Hariki, Mathias Winder +6
We study and hard x-ray photoemission spectra (XPS) in a series of late transition metal oxides: FeO (3), FeTiO (3), CoO (3) and NiO (3$d…
Charge transfer and tunable built-in electric fields across semiconductor-crystalline oxide interfaces
Zheng Hui Lim, Nicholas F. Quackenbush, Aubrey Penn +10
Built-in electric fields across heterojunctions between semiconducting materials underpin the functionality of modern device technologies. Heterojunctions between semiconductors an…
Cooperative Effects of Strain and Electron Correlation in Epitaxial VO2 and NbO2
Wei-Cheng Lee, Matthew J. Wahila, Shantanu Mukherjee +9
We investigate the electronic structure of the epitaxial VO films in the rutile phase using the density functional theory combined with the slave spin method (DFT+SS). In DFT-S…
Tailoring Materials for Mottronics: Excess Oxygen Doping of a Prototypical Mott Insulator
Philipp Scheiderer, Matthias Schmitt, Judith Gabel +7
The Mott transistor is a paradigm for a new class of electronic devices---often referred to by the term Mottronics---, which are based on charge correlations between the electrons.…
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…
