First-Principles Study of the Temperature Dependence of Structural, Electronic, and Hyperfine Properties of the Cu(100) Surface
Germán N. Darriba, R. Faccio, Mario Rentería
In this work, we investigate the temperature-dependent behavior of the pure (undoped) Cu(100) surface using first-principles calculations within the Density Functional Theory frame…
"Aftereffects'' Phenomenon in In(Cd)-Implanted -AlO Single Crystals: Novel Approach Integrating Experimental Double-Model Analysis with Density-Functional Theory
Germán N. Darriba, Reiner Vianden, Alejandro P. Ayala +1
We develop an experimental double-model analysis, combined with density-functional theory (DFT), to explore the origins of dynamic hyperfine interactions (HFIs) linked to the elect…
Experimental TDPAC and Theoretical DFT Study of Structural, Electronic, and Hyperfine Properties in (In-->) Cd-Doped SnO Semiconductor: Ab Initio Modeling of the Electron-Capture-Decay After-Effects Phenomenon
Germán N. Darriba, Emiliano L. Muñoz, Artur W. Carbonari +1
In this paper we investigate the effect of Cd doping at ultra-low concentrations in SnO both experimentally, by measuring the temperature dependence of the electric quadrupole…
The role of metallic impurities in oxide semiconductors: first-principles calculations and PAC experiments
L. A. Errico, G. Fabricius, M. Renteria
We report an ab-initio comparative study of the electric-field-gradient tensor (EFG) and structural relaxations introduced by acceptor (Cd) and donor (Ta) impurities when they repl…
Magnetic and structural study of Cu-doped TiO2 thin films
C. E. Rodríguez Torres, F. Golmar, A. F. Cabrera +5
Transparent pure and Cu-doped (2.5, 5 and 10 at. %) anatase TiO2 thin films were grown by pulsed laser deposition technique on LaAlO3 substrates. The samples were structurally char…
Appearance of room temperature ferromagnetism in Cu-doped TiO films
S. Duhalde, M. F. Vignolo, C. Chiliotte +6
In recent years there has been an intense search for room temperature ferromagnetism in doped dilute semiconductors, which have many potentially applications in spintronics and opt…
