Chem. Sol. State VL - 18 IS - 2 SE - Scientific articles DO - 10.15330/pcss.18.2.151-157 UR - https://journals.pnu.edu.ua/index.php/pcss/article/view/676 SP - 151-157 AB - <p align="justify">In the paper the InAs/Ga<em><sub>x</sub></em>In<sub>1-<em>x</em></sub>As superlattice system of small size cubic QDs (10&nbsp;nm) has been considered. Dispersion relations for electron and hole subbands have been calculated for superlattices of different dimensionality. The dependences of the interband absorption coefficient on light frequency, quantum dot size and interdot distance have been researched.It is shown, that the dimension of the superlattice has influence on the shape of the absorption bands and the increasingof the distance between quantum dots is followed by narrowing of the absorption peaks for all three superlatticetypes.</p> ER -
