Study of direct and indirect exciton states in GaAs-Ga1-xAlxAs quantum dots under the effects of intense laser field and applied electric field
(SPRINGER, 2012)
The effects of intense laser radiation on the exciton states in GaAs-Ga1-xAlxAs quantum dots are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations ...
