Chemical vapor deposition (CVD) method was utilized to synthesize single-crystal AlB12 nanorods on Si substrates in the high temperature horizontal furnace under H2 and Ar atmosphere, using Al powders and BCl3 gas as precursors without any catalysts. The morphology, crystal structures and components of the AlB12 were examined by scanning electron microscope (SEM), high-resolution transmission electron microscope (HRTEM), selected-area electron diffraction(SAED) and energy disperse spectrometer (EDS). SEM shows that the as-synthesized nanowires with the diameter ranging from 100nm to 350 nm and length ranging from several nanometers to several micrometers. HRTEM, SAED, and EDS reveal that the AlB12 nanorods are crystals elongated along the [020] direction. And growth mechanism based on the self-catalyst process is proposed for the formation of the AlB12 nanorods.
Key words： AlB12; nanorods; boron-riched compounds
