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.

在受主缺陷扩散层中费未能级的变化是线性的。

The level changes linearly in the acceptor defect layers.
