The aim of the study: to investigate the influence of external electric and magnetic fields and the concentration of donors of heterostructures on the optical properties of these heterostructures. Research methods: theoretical. Theoretical and practical results and novelty: The total optical absorption coefficient in GaAs Razavi-like delta-doped quantum wells under the action of external electric and magnetic fields was calculated and analyzed firstly. The origin of Friedel-like oscillations arising in the density profile generated by the filling of internal and surface electronic states is discussed. 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 Vasylieva Iryna V Demediuk Roman O. Kostenko Volodymyr M.
