研究了氢对反应溅射制备的一系列非晶硅H合金结构和压力诱导向金属态转变的影响。随着H原子浓度的增加，合金的x射线衍射干涉函数和对分布函数发生了系统的变化。在室温下，合金在200 kbar附近发生了压力诱导转变，并伴随着金属电阻率的连续下降。在180kbar下压缩后，恢复了一种呈四方结构的晶型。
The effect of hydrogen on the structure and the pressure-induced transition to the metallic state has been studied for a series of amorphous SiH alloys prepared by reactive sputtering. The systematic changes in the x-ray diffraction interference function and the pair distribution function are observed in these alloys with increasing concentration of H atoms. The pressure-induced transition, accompanied by a continuous decrease to a metallic resistivity, occurs at room temperature in the alloys near 200 kbar. A crystalline polymorph which appears to be a tetragonal structure is recovered after the compression at 180 kbar.
