Abstract

Abstract:

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 BCl₃gas 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 AlB₁₂nanorods.

Key words: AlB₁₂, nanorods, boron-riched compounds
