Journal ArticleDOI
Origins of the p -type nature and cation deficiency in Cu 2 O and related materials
TL;DR: In this article, a first-principle calculation of equilibrium nonstoichiometry and defect stability is proposed to explain why oxides are both $p$-type and naturally cation-deficient, whereas in other oxides (e.g., ZnO and MgO), they lead to localized, nonconductive states.
Journal ArticleDOI
Charge self-regulation upon changing the oxidation state of transition metals in insulators.
TL;DR: It is shown that signatures of oxidation states and multivalence—such as X-ray photoemission core-level shifts, ionic radii and variations in local magnetization—that have often been interpreted as literal charge transfer are instead a consequence of the negative-feedback charge regulation.
Journal ArticleDOI
The quest for dilute ferromagnetism in semiconductors: Guides and misguides by theory
TL;DR: Theoretical methods have greatly influenced experiment in search of the elusive marriage between semiconductor electronics and magnetism, and the development of spintronics as mentioned in this paper, but realizing the limitations and strengths of theoretical approaches promises a straighter course.
Journal ArticleDOI
Magnetic Interactions of Cr-Cr and Co-Co Impurity Pairs in ZnO within a Band-Gap Corrected Density-Functional Approach
TL;DR: In this paper, the magnetic coupling of the impurity pairs was determined in the presence of a correctly positioned conduction band (with respect to the $3d$ states) through the addition of empirical nonlocal external potentials to the standard density functional Hamiltonian.
Journal ArticleDOI
Electronic structure, donor and acceptor transitions, and magnetism of 3d impurities in In2O3 and ZnO
TL;DR: In this article, the authors employ a band-structure-corrected theory, and present simultaneously the chemical trends for electronic properties, carrier doping, and magnetism along the series of transition-metal impurities in the representative wide-gap oxide hosts.
