MgxZn1-xO Nanorod Arrays Synthesized by Pulsed-Laser Deposition
-
Abstract
MgxZn1-xO nanorod arrays were synthesized on Si(100)substrates using a catalyst.free pulsed.1aser deposition (PLD)method for the first time.The results of scanning electron microscopy indicate that the nanorods arrays of about 30～ 50nm in diameter and 60nm in length are grown on a nanocrystaUine ZnO film with a thickness of～70nm. Both the (002) peak in XRD and the near band emission in PL spectra are shifted by a certain extent comparing with that of pure ZnO thin film，indicating that the substitution of Zn sites by Mg atoms changes the crystal lattice constants and band gap of ZnO.The mechanism of the nanorods growth was also discussed.-
