查询词典 impurities

After comparing with the thermal conductivity under two different conditions, the thermal conductivity with vacancy is lower than that with Kr, which accounts for phonon scattering on impurities due to lattice strain is stronger than that due to differences in mass between the defect and the surrounding matrix.

模拟结果显示，温度在20~80K之间，考虑热膨胀时的导热系数比晶格常数固定时的值要低，但随温度变化的关系更加接近实验值时的情况；比较固体氩中不同掺杂时导热系数大小，发现同样掺杂浓度条件下，掺空穴时材料导热系数比掺氪时低，说明掺杂时由于晶格不匹配引起的声子散射比不同质量引起的散射更重要。
