Mixed optical phonon modes in semiconductor nanocrystals synthesized in porous ...
Belogorokhov, Alexander; Belogorokhova, Lyuba; Miranda, R. P.; Vasilevskiy, Mikhail; Gavrilov, S. A.This work is devoted to experimental and theoretical studies of optical phonons confined in CdS nanocrystals grown inside a porous alumina matrix. The complete sets of phonon modes, confined in a spherical quantum dot and in a cylindrical quantum wire, are considered in the framework of a continuum model, which allows the mixing of all the expected types of vibrations. It is shown that the calculated phonon-rel...
