Influence of effective mass in modulating size-dependent linear and non-linear polarization of single carrier 2-dimensional anharmonic quantum dots

Abstract

We explore the influence of effective mass ( m * ) on size-dependent linear and non-linear optical (NLO) response of one electron quantum dots in two dimensions with anharmonicity in the confinement potential. For some fixed values of transverse magnetic field strength ( ω c ), harmonic confinement potential ( ω 0 ), and anharmonic coupling strength ( λ ), the interplay between the dot size ( L) and dot effective mass ( m * ) in modulating the linear ( α ), the first ( β ), and the second ( γ ) NLO responses of the system is computed through a linear variational route. The investigation indicates a complicated interplay between the two controlling parameters.
