我们已经通过碳取代技术在硼蜂窝中成功地在NbB2（0001）表面的整个宏观区域上生长出具有高结晶质量的均匀BC3蜂窝片。这是第一个具有单层厚度的宏观均匀单晶BC3片。到目前为止，只生产出半径为几纳米的BC3微晶体。采用XPS、AES、LEED、STM、ARUPS和HREELS等测试手段对板材的性能进行了研究。在原子结构、化学浓度和声子结构等方面的实验数据和理论计算表明，均匀的BC3蜂窝片以外延的方式生长在衬底晶格上。(C) 2005 Elsevier Ltd版权所有。
We have successfully grown a uniform BC3 honeycomb sheet with high crystalline quality over the entire macroscopic area of the NbB2 (0001) surface by carbon-substituted technique in a boron honeycomb. This is the first macroscopic uniform sheet of single-crystal BC3 with a monolayer thickness. So far, only BC3 micro-crystals with radii of a few nanometres were produced. The properties of the sheet have been investigated by using XPS, AES, LEED, STM, ARUPS and HREELS. All the experimental data and the theoretical calculations, which are concerning with atomic structure, chemical concentration, and phonon structure, indicated that the uniform BC3 honeycomb sheet was grown in an epitaxial manner to the substrate lattice.
