Manipulating Mn--Mg cation complexes to control the charge- and spin-state of Mn in GaN
Thibaut Devillers, Mauro Rovezzi, Nevill Gonzalez Szwacki +15
Owing to the variety of possible charge and spin states and to the different ways of coupling to the environment, paramagnetic centres in wide band-gap semiconductors and insulator…
The Mn site in Mn-doped Ga-As nanowires: an EXAFS study
F. d'Acapito, M. Rovezzi, F. Boscherini +5
We present an EXAFS study of the Mn atomic environment in Mn-doped GaAs nanowires. Mn doping has been obtained either via the diffusion of the Mn used as seed for the nanowire grow…
Interface-driven phase separation in multifunctional materials: the case of GeMn ferromagnetic semiconductor
Emmanuel Arras, Frédéric Lançon, Ivetta Slipukhina +11
We use extensive first principle simulations to show the major role played by interfaces in the mechanism of phase separation observed in semiconductor multifunctional materials. W…
Structural and paramagnetic properties of dilute Ga1-xMnxN
Wiktor Stefanowicz, Dariusz Sztenkiel, Bogdan Faina +10
Systematic investigations of the structural and magnetic properties of single crystal (Ga,Mn)N films grown by metal organic vapor phase epitaxy are presented. High resolution trans…
Local structure of (Ga,Fe)N and (Ga,Fe)N:Si investigated by x-ray absorption fine structure spectroscopy
Mauro Rovezzi, Francesco D'Acapito, Andrea Navarro-Quezada +6
X-ray absorption fine-structure (XAFS) measurements supported by {\em ab initio} computations within the density functional theory (DFT) are employed to systematically characterize…
