quantum dots, coordinate-dependent effective mass, cadmium telluride


Theoretical studies of the energy spectrum of quantum dots are often carried out using the effective mass approximation with the parameters of the calculation set by the corresponding values of the bulk material of both the dot itself and its surroundings. In this study, the effective mass is a coordinate-dependent function, and its dependence on the coordinate is determined by the atomic structure of the quantum dot, which, in turn, is calculated by the density functional method. Both an unpassivated quantum dot and one passivated with thiol-glycolic acid are considered.
