We present a simulation to characterize the dependence on hydrostatic pressure for the photoluminescence spectra in self-assembled quantum dots with lens shape geometry. We have tested the physical effects of the band offset and electron-hole effective masses on the optical emission in dot lens. The model could be implemented to get qualitative information of the parameters involved in the quantum dot or the measured optical properties as function of pressure.

We have evaluated the influence of the built-in strain in InAs dots on the band gap following the treatments of strained layers reported in Ref. 33.
43.
The band-gap linear pressure coefficients were evaluated according to the nonlinear elasticity theory following Refs. 31 and 33. This treatment explains the lower value of the coefficient for strained InAs relative to the unstrained bulk value. The model assumes a simple strain two-dimensional layer.
