Notes:
The transverse-optical (TO) phonon energy in strained InAs quantum wells has been investigated by using far-infrared absorption. We observe that the TO phonon energy decreases when the misfit-induced biaxial tension in the InAs single quantum well is increased. Our result shows a stronger phonon energy dependence on the strain than the one reported by Cerdeira et al. [Phys. Rev. B 5, 580 (1972)]. The discrepancy may be explained by stress relaxation near the surface in their experiment. The application of our result will be discussed.
