For two lowest observed energy levels of quantum dot the density of states are mapped and correlated with the shape of quantum dot. Relation between inhomogeneous stress distribution in non symetrical quantum dots and the lowest energy level splitting was found. 2014 JA 6 4 R 4r 20231122135653.0 RVO:67985882 RVO:68378271 RVO:67985556 http://hdl.handle.net/11104/0222094 S NANOSCIENCENANOTECHNOLOGY|PHYSICSCONDENSEDMATTER 1.436 0.386 5.I 0.01597 0.399 5958 267 0.683 ScienceCitationIndex Q2 28.551 52.177 Q3 Q3 2013 Soubory v repozitáři: UFE 0393323.pdf 84872098760 SCOPUS 000331131900010 WOS cav_un_epca*0255709 Physica E: Low-Dimensional Systems and Nanostructures 1386-9477 1873-1759 Roč. 48 č. 1 2013 61 65 Elsevier
