內容簡介The oxygen donor adducts of dimethylzinc [Me2Zn(L)] (Ltetrahydrofuran, tetrahydropyran, or furan) are used without pre-reaction with oxygen for the growth of ZnO by liquid injection metal-organic (MO)CVD over the temperature range 350–550 8C. Vertically-aligned ZnO nanowires are deposited in a narrow temperature range centered on 500 8C. At other deposition temperatures, the ZnO films show continuous polycrystalline morphologies. At room temperature, the ZnO nanowires exhibit intense near band-edge photoluminescence (PL) at emission energies of 3.26 to 3.28 eV, and show minimal defect-related visible emission. Analysis of the ZnO nanowires by Auger electron spectroscopy (AES) shows that they are of high purity, with carbon not detected at an estimated detection limit of 0.5 at..
