Effect of quantum dot size and size distribution on the intersublevel transitions and absorption coefficients of III-V semiconductor quantum dot

摘要: The intersublevel absorption peak energy and coefficient of non-uniform quantum dot (QD) ensembles are calculated analytically. effect size variations distribution QDs on their states is analyzed. dots considered as a box with finite potential at the barriers described by Gaussian function. influence aspect ratio (base to height ratio) optical transitions studied. Our model predicts (height base) accurately determine peaks corresponding coefficient. We also compute QD different distributions verify results using this reported experimental other theoretical results.
