C-V Data and Geometry Parameters of Self-Assembled INAS/GAAS Quantum Rings

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

In present work we focus on these problems and on the interpretation of the recent CV data given in W. Lei, C. Notthoff, A. Lorke, D. Reuter and A. D. Wieck (Appl. Phys. Lett. 96, [...]

The INGAAS/GAAS Quantum Dots Under Effective and Ab Initio Treatments: Comparison and Results

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

An effective approach for describing the electronic structure of InGaAs/GaAs quantum dots (QDs) is presented. We model QDs based on a single sub-band approach with an energy dependent electron effective mass. The model assumes that [...]

INGAAS/GAAS Quantum Dot With Material Mixing

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

We model an InGaAs/GaAs quantum dot having dependence of the Ga fraction along vertical axis. The effect of material mixing on the electron energy spectra is considered. This theoretical model is based on a single [...]

Numerical Simulation of Electronic Properties in Quantum Dot Hheterostructures

Vlahovic B., Filikhin I., Suslov V.M., Wang K., North Carolina Central University, US

Because of the strong dependence of energy level on the geometry and sizes, the quantum dots are perfect candidates as high efficiency photovoltaic solar cells. Efficiency of 63.2% solar cell has been predicted by theoretical [...]

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 [...]
