Abstract
Hexagonal AlN nanotowers/nanorods with a diameter of hundreds of nanometers and a length of several microns have been successfully synthesized by direct nitridation of Al and rice bran mixture compacts in a tube furnace up to 1250°C in a nitrogen flow without addition of extra catalyst. The structure of the nanoAlN products was characterized by XRD and SEM. The formation mechanism of the nanotowers/nanorods is due to the existence of rich trace elements in the rice bran. The importance of these trace elements and the formation of AlN nanotowers/nanorods have been discussed with the VLS/VS growth mechanism. The unique morphology of the nanotowers could be useful for studying fundamental physical phenomena and for fabricating nanodevices. Copyright © 2010 MS&T'10®.
