摘要：

We investigate the effect of phonon confinement on the optically-detected electrophonon resonance (ODEPR) effect and ODEPR line-width in cylindrical quantum wires. The ODEPR conditions as functions of the wire's radius and the photon energy are also obtained. The shifts of ODEPR peaks caused by the confined phonon are discussed. The numerical result for the GaAs/AlAs cylindrical quantum wire shows that in the two cases of confined and bulk phonons, the line-width (LW) decreases with increasing wire's radius and increases with increasing temperature. Furthermore, in the small range of the wire's radius (R <= 30 nm) the influence of phonon confinement plays an important role and cannot be neglected in reaching the ODEPR line-width.
