Structural and optical properties of Zn0.9 Mn0.1 O/ZnO core-shell nanowires des...
Kaydashev, V.E.; Kaidashev, E.M.; Peres, M.; Monteiro, T.; Correia, M.R.; Sobolev, N.A.; Alves, L.C.; Franco, N.; Alves, E.Core-shell ZnO/ZnMnO nanowires on a-Al2O3 and GaN (buffer layer)/Si (111) substrates were fabricated by pulsed laser deposition using a Au catalyst. Two ZnO targets with a Mn content of 10% were sintered at 1150 and 550 °C in order to achieve the domination in them of paramagnetic MnO2 and ferromagnetic Mn2O3 phases, respectively. Cluster mechanism of laser ablation as a source of possible incorporation of seco...
