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...

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...
We calculate variationally the binding energy of excitons in type-Ⅱ quantum well structures with the staggered or the misaligned configuration. Particularlly, we have investigated the effect of the longitudinal electric field on the exciton binding energy in In1-xGaxAs/GaSb1-yA.sy systems. It is...

Binding energies of excitons in II-VI compound-semiconductor based quantum well structures We present a brief description of the calculation of the variation of the binding energy of the heavy-hole exciton as a function of well width in quantum w... RT Senger,KK Bajaj - 《Physica Status Solid...
The binding energy of excitons in a semiconductor (e.g., GaAs) quantum well to each other and to neutral donors is calculated variationally using the six-parameter wave function of Brinkman, Rice, and Bell. The biexciton results for well... DA Kleinman - 《Phys.rev.b》 被引量: 290发...
Basing on the PL and RC spectra of bulk crystals we determine the energy of the ground and first four excited states of both excitons, which follow the usual hydrogenic Rydberg series of energy levels of 3D excitonic states (En = Ry*/n2). From the numerical fit we estimate that the...
