In the present study, the effects of varying doping concentration and applied electric field on the intersubband-related optical absorption and relative refractive index change coefficients in modulation-doped GaAs/AlxGa1-xAs ...

In this work we reported the theoretical calculations of the absorption coefficient in a GaAs/AlxGa1−xAs core/shell spherical quantum dot as a function of the aluminium concentration x in the direct band-gap regime, and ...
