Exciton states in quasi-zero-dimensional semiconductor nanosystems
- National Academy of Sciences of Ukraine, Kurdyumov Institute for Metal Physics (Ukraine)
The variational method in the context of the modified effective mass approximation is used to calculate the dependence of exciton ground-state energy for a quantum dot embedded in a borosilicate glassy matrix on the quantum dot radius. It is shown that the peaks in the absorption and low-temperature luminescence spectra of such a nanosystem are shifted to shorter wavelengths due to size quantization of the exciton ground-state energy in the quantum dot.
