摘要：
In this paper, the effects of the incident light polarization on the bound to continuum absorption coefficient of both spherical and conical quantum dots have been investigated. The study is based on the effective mass theory and the non equilibrium Green’s function formalism. For the bound to continuum component of the absorption coefficient, both of in-plane and perpendicular polarization effects have been studied for different sizes of conical and spherical quantum dots. Generally, the behavior of conical and spherical quantum dots are similar in case of perpendicular polarization, but their behaviors are different in the case of in-plane polarization.
