Excitons in inhomogenous quantum nanospheres have been theoretically studied within the effective mass approximation. An infinite deep potential has been used to describe the effects of quantum confinement. The binding energy with or without an applied electric field is determined by the Ritz variational...

We study the binding energy of excitons in a cylindrical GaAs/Ga1−xAlxAs nanowire superlattice, embedded in Ga1−yAlyAs matrix, in the presence of magnetic and electric fields applied parallel to the growth direction. We express the exciton trial function as a product of one-particle wave...

Binding energy of the complex ( D + - X ) with Γ- X mixing in GaAs/AlAs quantum wells The binding energy of excitons to ionized shallow donors in a GaAs/AlAs quantum well in the vicinity of the type-I to type-II transition is obtained for im... IC Cunha Lima,A Ghazali,PD Emmel...
It is found that the binding energy of the ground state of an exciton formed from an electron and a hole spatially separated from each other (the hole is moving within a quantum dot, and the electron is localized above the spherical (quantum dot)–(insulating matrix) interface) in a nano...

The binding energy of excitons in symmetric and asymmetric coupled double GaAs/Ga_(1-x)Al_xAs quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic field, as a function of the potential symmetry, size of the quantum...
Excitons in type-II quantums dots: Binding of spatially separated electron and hole The quantum size effect for the binding energy of an exciton in a spherical quantum dot is studied theoretically. We use a variational approach and assume that the electron and hole are separated by infinite ...
