It is belived that two scattering peaks are related to coupling modes between plasmon and longitudinal optical phonon for Si-doped GaAs/AlGaAs superlattice.
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。
The AlAs LO modes confined in AlAs layers and GaAs like LO modes confined in Al x Ga 1- x As layers were observed in AlAs/Al x Ga 1- x As superlattices under off resonance conditions.
报道不同层厚的AlAs/AlxGa1-xAs及GaAs/AlxGa1-xAs短周期超晶格的纵光学声子模的室温喇曼散射测量结果。
