In an ideal perfect solid, the phonon propagated by an unattenuated plane wave。 that is to say， the phonon correlation length is not restricted, the performance registers as momentum conservation in the Raman scattering, and the phonon can be excited only in the Brillouin zone center。At room temperature，the first-order Raman peak of monocrystalline silicon is at 525cm-1,which its half-width is 2.25cm-1, and its second-order one is near 970cm-1
有误之处请指正，别笑话哈 |
