+
+SiC has many excellent properties and wide applications.
+
+Phonons in SiC are important. They can influence the properties of SiC and can be used to characterize the materials.
+
+There are many existing studies on phonons in SiC, but they have some shortcomings.
+
+In this paper, we do some things. We do something for the first time.

+\subsection{Phonons in Perfect 4H-SiC}
+
+% 我们计算了 4H-SiC 在 A-Gamma 和 Gamma-M 上的声子频率，如图和附录1所示。
+% 在拉曼散射中，起作用的模式都是那些非常接近于 Gamma 的模式
+%   （如图中的点所示，分为位于 1/50 和 1/100 处，这两条线分别对应于拉曼散射在 z 方向入射/散射和 y 方向入射/散射）。
+% 大多数声子模式在 Gamma 附近都是连续的，这使得它们的频率对入射光的方向不敏感；
+%   然而，少数声子具有较强的极性，这使得声子之间存在长程的库伦相互作用（引用文献），并导致 gamma 附近的频率不同，如图中的某两条线所示。
+% 据此，我们将无缺陷的 4H-SiC 的声子分成三类：
+%   无拉曼活性或拉曼散射强度太弱的模式，它们在拉曼散射谱上不可见；
+%   拉曼散射强度足够大且极性不强的模式，它们在拉曼散射谱上可以看到，且频率与拉曼入射光方向无关；
+%   极性声子，它们在拉曼散射谱上可以看到，不仅频率与入射光方向有关，而且可与载流子发生一些相互作用。
+
+Phonons in defect-free 4H-SiC are calculated at A-$\Gamma$ and $\Gamma$-M,
+  as shown in Figure \ref{fig:phonon} and Table \ref{tab:phonon}.
+Raman active phonons are very close to $\Gamma$,
+  as indicated by the points in the figure.
+Because of the consistency of the most phonon modes near $\Gamma$,
+  most of the phonon frequencies are insensitive to the direction of the incident light.
+However, some phonons have strong polarities,
+  which leads to long-range Coulomb interactions between phonons,
+  and results in different frequencies near $\Gamma$,
+  as shown by the two lines in the figure.
+Thus, we divide the phonons of defect-free 4H-SiC into three categories:
+  (1) Raman inactive or too weak Raman intensity,
+    which are invisible in the Raman scattering spectrum;
+  (2) Raman active phonons with strong polarities,
+    which are visible in the Raman scattering spectrum,
+    and their frequencies are independent of the direction of the incident light;
+  (3) Polar phonons,
+    which are visible in the Raman scattering spectrum,
+    and their frequencies depend on the direction of the incident light,
+    and can interact with carriers.
