Effect of Wannier-Mott Exciton on Semiconductor Quantum Dot Photo-Absorption Spectra
A review of the Wannier-Mott exciton and the quantum dot as a spherical infinite potential well are presented and used to analyze the effect of the exciton binding energy and quantized energy states on absorption spectra for semiconductor nanocrystallites. The ratio of semiconductor to exciton Bohr radius is used to categorize the exciton and confinement […]
