本论文主要研究声子频率和掺杂点缺陷浓度对同位素掺杂硅声子散射的影响。
This paper focuses on the phonon frequency effect and the isotope-doped concentrates effect on the phonon scattering in isotope-doped Si.
这些晶体通过对声子进行操控来工作；声子是一种振动波，可以携带声音或热量，具体携带什么则取决于其频率的高低【 译者注：声子是晶体点阵振动能的量子 】。
The crystals work by manipulating phonons, or vibrational waves that can carry either sound or heat depending on the frequency.
这些结果会对在较宽频率和较大掺杂浓度下构造声子热传导公式有帮助，同时有利于开展下一步工作。
These results could be helpful both for formulizing the phonon thermal conductivity in a wider frequency region including non dispersive and dispersive phonon and for performing our further work.
