Electron Effective Mass Of GaAs Double-Concentric Quantum Rings

Filikhin I., Deyneka E., Vlahovic B., North Carolina Central University, US

We carried out the calculations for the single carrier energy levels, and the optical transitions of these structures, with taking into account the effects resulting in change of the electron effective mass due to the [...]

Numerical Modelling of Experimentally Fabricated Inas/Gaas Quantum Rings

Filikhin I., Deyneka E., Vlahovic B., North Carolina Central University, US

In the presented work we apply a single subband model for InAs/GaAs QD(QR), where the electron effective mass depends on the confinement energy by the Kane formula. The geometrical parameters of the model are based [...]

Size Related Contribution to Electron Energy of the Quantum Ring

Filikhin I., Deyneka E., Melikian H.M., Vlahovic B., North Carolina Central University, US

The semiconductor quantum ring (QR) is studied under energy dependent effective mass approximation. The 3D ground state (confined) energy problem is solved numerically by the finite element method in a single subband approach. We obtained [...]

Electron Energy States of INAS/GAAS Quantum Ring Array

Filikhin I., Deyneka E., Melikian G., Vlahovic B., North Carolina Central University, US

Planar array of semiconductor quantum rings is studied under the energy dependent effective mass approximation. Rectangular shape InAs quantum rings (QR) are embedded into the GaAs substrate. The 3D confined energy problem is solved numerically [...]

InAs/GaAs Quantum Ring in Energy Dependent Quasi Particle Effective Mass Approximation

Filikhin I., Suslov V.M., Deyneka E., Vlahovic B., North Carolina Central University, US

Considered is three-dimensional In/As quantum ring using energy dependent quasi-particle-effective-mass approximation. This model was first used by Y. Li et al. (Y. Li, O. Voskoboynikov, C.P. Lee, 2002 Technical Proceedings of International Conference on Modeling [...]
