Fabrication of Vertically Well-Aligned (Zn,Mn)O Nanorods with Room Temperature Ferromagnetism


  • This work was supported in part by the Korea Science and Engineering Foundation through the Quantum-functional Semiconductor Research Center at Dongguk University in 2005 and in part by the project for “National Research Laboratory” sponsored by the Korea Institute of Science and Technology Evaluation and Planning (KISTEP). High-resolution XRD using synchrotron radiation was carried out at the 3C2 beamline at Pohang Accelerator Laboratory (PAL).

Vertically well-aligned (Zn,Mn)O nanorods (see Figure) that show ferromagnetic behavior at room temperature have been grown on sapphire substrates by chemical vapor deposition. The high optical quality of the nanorods has been demonstrated by photoluminescence spectroscopy. These nanowires may find use in future nanoscale magneto-optic and magneto-electronic applications.
