Interband Absorption of Light by Quasi-Zero-Dimensional Nanosystems
The results of theoretical and experimental investigations of interband absorption of light in semiconductor spherical nanocrystals are analyzed. As shown, the absorption threshold in a nanocrystal is shifted to shorter wavelengths if the polarization-related interaction of electrons and holes with...

| description | The results of theoretical and experimental investigations of interband absorption of light in semiconductor spherical nanocrystals are analyzed. As shown, the absorption threshold in a nanocrystal is shifted to shorter wavelengths if the polarization-related interaction of electrons and holes with the nanocrystal surface is taken into account. As ascertained, the absorption edge for nanocrystals is formed by two transitions comparable in intensity. These transitions occur from different levels of size-related quantization for a hole to the lower level of size-related quantization for an electron. |
