纵声子 [zòng shēng zǐ]
[物] longitudinal phonon
- 不少极性晶体，电子与表面声学声子、体纵光学声子耦合弱，但与表面光学声子耦合强。
There is a weak coupling between electrons and BO SA phonons but a strong coupling between electrons and SO phonons for many polar crystals. - 理论分析认为，这两个散射峰是掺杂超晶格的等离子激元与纵光学声子耦合模引起的。
It is believed that two scattering peaks are related to coupling modes between plasmon and longitudinal optical phonon for Si-doped GaAs/AlGaAs superlattice. - 有不少极性半导体，电子与体纵光学声子的耦合弱，但与表面光学声子的耦合强。
There isa weak bulk coupling but a strong surface coupling between electrons and phonons for many ionic crystals. The properties of a surface polaron in a polar semiconductor are studied.
