Influence of confined phonon for the different models in GaAs quantum wells on the optically detected electrophonon resonance linewidth
- Quang Tri Teacher Training College (Viet Nam)
In this work, we use method of the operator projection to study in detail the influence of phonon confinement, which depicted in the Huang-Zhu models, Ridley’s guided, and Fuchs–Kliewer slab on the optically detected electrophonon resonance (ODEPR) effect and ODEPR linewidth in square quantum wells. In addition, the ODEPR linewidths the same as functions of the width of well and temperature are also achieved. By numerical calculations for quantum well of the GaAs, we can see that the linewidth reduces with respect to the width of the well and raises with temperature for the cases of bulk and confined phonons. Moreover, we cannot ignore the important role of the influence of phonon confinement in the narrow area of the width of well (L{sub z}<10 nm), when considering the ODEPR linewidths.
