Qubit Entanglement from a Bipartite Atomic System in a Carbon Nanotube

Bondarev I.V., Vlahovic B., North Carolina Central University, US

The development of materials that may host quantum coherent states is a critical research problem for the nearest future. Important would be to demonstrate quantum information transfer between two quantum bits arbitrarily separated in the [...]

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 [...]

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 [...]
