利用离子通道和核反应分析研究了氢化晶体硅中硼和氢原子所占据的晶格位置。氢化后，硼原子被发现从取代位移位。数据分析表明，位移为0.22±0.04 Å。发现氢原子优先占据键中心位置。这些发现与硼氢配合物的结构一致，其中氢原子占据硅原子和硼原子之间的位置，而硼原子松弛回三倍协调的位置。这些数据与最近对硅中BH配合物结构的预测进行了比较。
The lattice site occupied by the boron and hydrogen atoms in hydrogenated crystalline silicon is investigated by use of ion channeling and nuclear-reaction analysis. After hydrogenation, boron atoms are found to be displaced from substitutional sites. Analysis of the data indicates that the shift is 0.22±0.04 Å. The hydrogen atoms are found to preferentially occupy the bond-center site. These findings are consistent with a structure for the boron-hydrogen complex in which the hydrogen atom occupies a site between a silicon and a boron atom, while the boron atom relaxes back towards a threefold-coordinated position. The data are compared with recent predictions of the structure of the BH complex in silicon.
