The XRD curves indicate the sample has polycrystalline hexagonal wurtzite structure. The XRD data of the sample prepared at 250C and 300C has a bigger angle shift about 0.05and 0.3respectively. That indicate the structure of the sample has some changes. The EDS indicate the sample contains Zn  O and C. So the XRD shift may attribute to the C. The XPS indicate the C doped in the crystal lattice of ZnO of the sample prepared at 300C  and the sample prepared at 250C may be only a few of C doped in the crystal lattice of ZnO. The PL of the sample prepared at 300C only has a weak ultraviolet emission  which indicates C modified the nanocrystalline ZnO surface as a non-radiative recombination center. In this process C could non-radiatively recombine the carries on the nanocrystallin ZnO surface. The sample prepared at 250C has a strong visible emission at about 530 nm. This emission band could be attributed to oxygen vacancy because C schlepped some oxygen on the nanocrystalline ZnO surface.   Residual donors in undoped LEC InP 会议论文 11th international semiconducting and insulating materials conference (simc-xi), canberra, australia, jul 03-07, 2000 Zhao YW; Sun NF; Sun TN; Lin LY; Wu XW; Guo WL; Wu X; Bi KY 收藏  |  浏览/下载：14/0  |  提交时间：2010/10/29 INDIUM-PHOSPHIDE  CARBON  DEFECTS  GROWTH
