Abstract:The nonlinear optical properties of quantum dots under multidimensional confinement potential are investigated. In the framework of the effective mass approximation, the analytical formula of the optical absorption coefficient in the quantum dots is derived using the density matrix method and the iterative procedure, and the numerical results of typical Al0.3Ga0.7 As/GaAs material are calculated. Through calculation and numerical fitting, it is found that increasing temperature and the depth of limiting potent… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
