Exciton-related nonlinear optical properties in cylindrical quantum dots with asymmetric axial potential : combined effects of hydrostatic pressure, intense laser field, and applied electric field

ABSTRACT: The exciton binding energy of an asymmetrical GaAs-Ga1−xAlxAs cylindrical quantum dot is studied with the use of the effective mass approximation and a variational calculation procedure. The influence on this quantity of the application of a direct-current electric field along the growth d...
