摘要:
The strain configuration in CdTe/ZnTe strained‐layer superlattices has been measured by Raman scattering near resonance. The ZnTe‐like longitudinal optical phonon energy in the superlattice is significantly shifted from the bulk value to lower energies and the shift increases with increasing superlattice CdTe fraction. The observed shifts agree with calculations of strain shifts based on a free‐standing strain distribution.
