-模式频率在倒空间中的依赖性被仔细研究并展示在@figure-rev 中。
-各个模式在 gamma 点附近的色散关系被计算出来并被展示在图 a 中。
-在弱极性模式中，频率偏移在 1cm -1 以内；在极性模式中，频率的变化达到了 10 cm -1 量级。其中，
-E2 模式没有极性，因此在 Gamma 点处无色散；离开 Gamma 点越远，频率对入射方向的依赖越大。
-这意味着相比于绿光，使用紫外光入射时，正入射与侧入射的频率差异会更大。
-A1 的极性不为零，它们的色散呈现瓣状，意味着无论使用什么激光波长，频率的变化都比较接近。
-E2-3 的频率几乎不变并且在任何角度的入射实验中都清晰可见 ，可以被选定为实验中的校准参考。
-图b给出了实验结果，其中 E2-1 由于较弱，导致样本标准差较大；E2-2 和 A1-1 的散射强度较强，因此标准差较小。
-图c对比了实验与计算的结果，可以看到两者吻合较好，只有 A1-1 的实验结果明显大于计算结果。
-这可以归结为一些原因。
-我们的研究对比了入射方向对极性较弱的声子模式的影响并在理论上进行了解释，以实现对拉曼光谱的更精确分析，并为掺杂和载流子对光谱影响的分析做了准备。
