Optical, electrical and magnetic properties of transparent, n-type conductive Zn0.90-x,V0.10AlxO thin films elaborated from aerogel nanoparticles

Résumé

Vanadium-aluminium co-doped ZnO thin films have been grown by rf-magnetron sputtering of Zn0.90-xV0.10AlxO (x = 0.01 to 0.03) aerogel nanoparticles. Even though the films were deposited at room temperature they were of good crystal quality and showed c-axis texturing normal to the film surface. The films are highly transparent in the visible with a transmittance higher than 90%. The highest conductivity of 5.10(3) Omega(-1) cm(-1) is obtained for 1% Al doping. The incorporation of V, a notoriously difficult dopant in ZnO, is confirmed by the observation of different absorption bands near 800 nm which we attribute to intracenter transitions of Zn substituted V2+. The magnetic properties of the aerogel particles have been studied by electron paramagnetic resonance (EPR) spectroscopy. No evidence for a ferromagnetic phase is found contrary to theoretical predictions. (C) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
