The aim of the study: to investigate the influence of the geometric position of the heterostructures on the of the energy levels structure of these heterostructures. Research methods: theoretical. Theoretical and practical results and novelty: the energy- spectrum of vertically coupled quantum dot-ring depending on their general location is firstly calculated and analyzed. Moreover, the revealed boundary, crossing which, the heterostructures under consideration become uncoupled. Implementation efficiency: the acquired new knowledge helps to improve the understanding of the optical and electrophysical properties of the studied heterostructures. Scope (branch) of application: physics of nanostructure, growing and investigation of nanostructures. Product Description popup.authors Vasilieva Iryna V. Demediuk Roman O. Kostenko Volodymyr M.
