摘要：

We calculated the effects of the hydrostatic pressure and temperature on the binding energy for centric shallow donors in asymmetrical GaAs/AlGaAs quantum wells, within the effective mass approximation and variational approach. We found that the pressure, temperature and asymmetry effects are mainly observed when the quantum confinement due to the barrier potential are stronger.
