| 中文摘要 | Fe ions were implanted into ZnO single crystals with multiple energies between 50 and 380 keV up to a total influence of 12.5 x 10(17) cm (2). The crystal quality of Fe+ implanted ZnO was investigated by X-ray diffraction 2 theta scans and omega-rocking curve measurements. The appearance of Fe related diffraction peaks after 700 degrees C annealing of the implanted sample indicates possibly formation of Fe nanoparticles. Superconducting quantum interference device measurements revealed ferromagnetic behavior below 250 K for both the as-implanted and post-annealed ZnO. Photoluminescence and Raman scattering as well as X-ray rocking curve measurements all indicate introduction of structural defects after Fe implantation. Some of the defects act as nonradiative recombination centers, and suppress the visible and ultraviolet (UV) emission in ZnO. These defects also break the Raman selection rule, and lead to the activation of some silent phonon modes. Annealing of the implanted sample at 700 degrees C causes partial recovery of the defects, however, the X-ray diffraction results of the anneal ZnO show even an improvement of the crystal quality compared with the un-implanted one. This could be attributed to the recovery of the grown-in defects in ZnO. (C) 2009 Elsevier B.V. All rights reserved. |
