用斜棱镜冲击波实验确定了沿单晶硅三个轴传播的冲击波的压缩。当应力小于200kbar时，沿<110>和<1111>方向的激波呈现四种波结构。前三个波被认为与Hugoniot弹性极限和随后的两个多形相变有关。高能激光沿<100>轴的散射可能表明弹性波和第一相变波之间的混合。
Shock wave experiments with inclined prisms have been used to determine the compression for shocks propagated along three axes of single‐crystal Si. At stresses less than about 200 kbar, the shocks along the 〈110〉 and 〈1111〉 axes exhibited four wave structures. The first three waves were taken to be related to the Hugoniot Elastic Limit and to two succeeding polymorphic phase transitions. Scatter in the magnitude of the HEL along the 〈100〉 axis may indicate mixing between the elastic wave and the first phase transition wave.
