- 1. Phys. Rev. Lett. 98, 115503 (2007) , “Oxygen Vacancy Clustering and Electron Localization in Oxygen-Deficient SrTiO3: LDA+U Study”, Do Duc Cuong, Bora Lee, Kyeong Mi Choi, Hyo-Shin Ahn, Seungwu Han, and Jaichan LeeWe find, using a local density approximation +Hubbard U method, that oxygen vacancies tend to cluster in a linear way in SrTiO3, a prototypical perovskite oxide, accompanied by strong electron localization at the 3d state of the nearby Ti transition metal ion. The vacancy... (Read more)
- 2. J. Appl. Phys. 100, 044109 (2006) , “Variable energy positron beam analysis of vacancy defects in laser ablated SrTiO3 thin films on SrTiO3”, S. McGuire, D. J. Keeble, R. E. Mason, P. G. Coleman, Y. Koutsonas, and T. J. JacksonVacancies are known often to be the dominant type of point defects in perovskite oxides, but their presence can rarely be directly determined. Positron annihilation methods have unique sensitivity to vacancy-related defects and the variable energy positron beam (VEPB) techniques allow near-surface... (Read more)
