X-ray diffraction (XRD) and selected area electron diffraction pattern (SADP) results showed that the (Ga1-xMnx)N nanorods had preferential c-axial growth direction. Transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) images showed that one-dimensional (Ga1-xMnx)N nanorods without defects had c-axis-oriented crystalline wurzite structures. Atomic arrangements for the (Ga1-xMnx)N nanorods grown on the Al2O3 (0001) substrates are described on the basis of the XRD, the TEM, the SADP, and the HRTEM results.
