摘      要：We have calculated the intersubband transitions and the ground-state binding energies of a hydrogenic donor impurity in a quantum well in the presence of a high-frequency laser field and hydrostatic *** calculations are performed within the effective mass approximation,using a variational *** conclude that the laser field amplitude and the hydrostatic pressure provide an important effect on the electronic and optical properties of the quantum *** to the results obtained from the present work,it is deduced that(i)the binding energies of donor impurity decrease as the laser field increase,(ii)the binding energies of donor impurity increase as the hydrostatic pressure increase,(iii)the intersubband absorption coefficients shift toward lower energies as the hydrostatic pressure increases,(iv)the magnitude of absorption coefficients decrease and also shift toward higher energies as the laser field *** is hopeful that the obtained results will provide important improvements in device applications.
