Abstract

In this paper, the effect of constant effective mass and position-dependent effective mass on the optical properties of a spherical quantum dot has been studied. For this purpose, the intersubband optical absorption coefficient and the refractive index changes are obtained using both a constant effective mass and position-dependent effective mass. According to the results obtained from the present work, we find that spatially varying electron effective mass plays an important role in obtaining the intersubband optical absorption coefficients and refractive index changes in the finite and infinite quantum dots.
