Confined excitons, phonons and their interactions in Ge nanocrystals embedded in SiO2

PDF Version Also Available for Download.

Description

The authors report the resonant Raman scattering of the optical phonon in Ge nanocrystals with radius ranging from 2 to 5 nm. They have observed the effect of quantum confinement on both the optical phonon and the E{sub 1} exciton. The confinement energy of the E{sub 1} exciton has been explained within the effective mass approximation.
