Reduced ceria (CeO2−x ) has a rich phase diagram comprising a variety of bulk phases with stoichiometries ranging from CeO2 to Ce2O3 as the reduction conditions are increased. Some observed reduced ceria (111) surface reconstructions are terminatio

Tuning the insulator-metal transition in oxide interfaces: an ab initio study exploring the role of oxygen vacancies and cation interdiffusion
Autor: Ferrari, Valeria Paola, Weissmann, Mariana Dorotea
We investigate the structural, electronic, and magnetic properties of a particular interface in the oxide heterostructures LaAlOmath formula/SrTiOmath formula (LAO/STO) and TiOmath formula-anatase/LaAlOmath formula (TiOmath formula/LAO), namely the i

Manganese deposited on the N-polar face of wurtzite gallium nitride [GaN (0001¯)] results in two unique surface reconstructions, depending on the deposition temperature. At lower temperature (less than 105∘C), it is found that a metastable 3×3 st

The prototype reducible oxide ceria is known for its rich phase diagram and its ability to absorb and deliver oxygen. The high oxygen storage capacity is the basis for the use of ceria in catalytic and sensor applications where the surface plays a pa

A Two-Dimensional Manganese Gallium Nitride Surface Structure Showing Ferromagnetism at Room Temperature
Autor: Abhijit Chinchore, Arthur R. Smith, Yingqiao Ma, V. Ferrari, M. A. Barral
Practical applications of semiconductor spintronic devices necessitate ferromagnetic behavior at or above room temperature. In this paper, we demonstrate a two-dimensional manganese gallium nitride surface structure (MnGaN-2D) which is atomically thi

Comment on 'Oxygen Vacancy Ordering and Electron Localization in CeO2: Hybrid Functional Study'
Autor: Gustavo E. Murgida, Ana María Llois, M. Verónica Ganduglia-Pirovano, V. Ferrari
Han et al. have recently published an article on the ordering of oxygen vacancies and electron localization in bulk CeO 2 using density functional theory (DFT) with the Heyd−Scuseria−Ernzerhof (HSE06) functional. On the basis of their results, th
