Multi-phonon Raman Scattering in GaAs/Al0.28Ga0.72As Super-lattice
Journal Title: Physical Science International Journal - Year 2017, Vol 16, Issue 3
Abstract
Raman scattering measurement of GaAs/Al0.28Ga0.72As super-lattice has been performed by an incident light with the wave-vector perpendicular to super-lattice growth axis at room temperature. Several peaks in Raman Scattering spectrum are observed. Theoretical analysis shows that the peak at 290 cm-1 may be caused by emission of a longitudinal optical phonon in GaAs/Al0.28Ga0.72As super-lattice, the peak at 584 cm-1 by emission of two ones, and the peak at 876 cm-1 by emission of three ones. The multi-phonon Raman scattering may be resulted from the folded optical phonons in super-lattices.
