晶体硼的结构单元是正二十面体,每个单元中有12个硼原子,每个硼原子与另外5个硼原子相连。是原子晶体。 熔点2573K,沸点2823K,相对硬度9.5(金刚石为10)
其原因是硼元素的掺入促进了金刚石单晶的(111)晶面生长,使受主能级提高,晶体的带隙变窄,载流子浓度提高。
It is indicated that the boron doping promotes the growth of (111) face of the diamonds, enhances acceptor level, narrow 's band gap and increases carrier concentration correspondingly.
