摘要/Abstract

摘要：

以铝(Al)粉末和三氯化硼(BCl₃)为前驱体, 以H₂和Ar分别作为还原气体和保护气体, 在高温水平电炉中采用化学气相沉积方法在Si衬底上原位制备了大量的AlB₁₂纳米棒. 利用扫描电镜(SEM), 高分辨透射电镜(HRTEM), 选区电子衍射(SAED), 能谱(EDS)表征了AlB₁₂纳米棒的形貌、晶体结构和成份. SEM结果表明纳米棒的直径在100~350 nm之间, 长度从几百个纳米到几个微米, TEM、SAED和EDS结果显示AlB₁₂纳米棒沿着[020]方向生长. 最后根据纳米线生长过程探讨了AlB12纳米棒的自催化生长机理.

关键词: AlB₁₂, 纳米棒, 富硼化合物

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
