不同方向入射光的声子位置不同。
声子的性质与它们在倒空间中的位置(即波矢)有关,而参与拉曼散射的声子波矢则由激光波长和拉曼入射配置(正入射、掠入射、边入射)决定。
在我们的实验(绿光)中,参与拉曼散射的声子都位于 Gamma 点附近(距离仅 xxx 埃),而与 Gamma 点的相对方向则根据入射配置而定。
在我们的实验(绿光)中,参与拉曼散射的声子都位于 Gamma 点附近(距离仅 0.005 埃),而与 Gamma 点的相对方向则根据入射配置而定。
对于正入射,声子大致位于 Gamma-A 线上;对于边入射,声子大致位于 Gamma-K 线上。对于掠入射,声子不位于任何高对称线上。
The properties of phonons depend on their positions in reciprocal space (i.e., their wavevectors),
and the wavevectors of phonons participating in a Raman scattering process
are determined by the Raman experiment configuration.
In our experiments (back-scattering with 532 nm laser light),
the phonons involved are located very close to the #sym.Gamma point (approximately $5.13 times 10^(-3) angstrom$),
the phonons involved are located very close to the #sym.Gamma point (approximately $5 times 10^(-3) angstrom$),
and direction relative to the #sym.Gamma point is determined by the incidence configurations.
For normal and edge incidence,
the relevant phonons lie approximately along the #sym.GammaA and #sym.GammaK lines, respectively,
