Molenkamp Energy relaxation in CdSe/ZnSe quantum dots under the strong exciton-phonon coupling regime Phys. Stat. Sol C: Conferences 3 (4) (2015-02-24 14:17:21), 924-927 Resonant photoluminescence and photoluminescence excitation spectroscopy have been applied to CdSe/ZnSe quantumdots where separation between the quantized levels is close to the optical phonon energy. Astrong relaxation enhancement induced by the optical phonon is observed. The fine structure of the phonon replicas is resolved. It is attributed to the optical phonons with large wave vectors from the symmetrical points of the Brillouin zone. http://onlinelibrary.wiley.com/doi/10.1002/pssc.200564743/abstract |
