Abstract

At a finite temperature, electron-electron interactions and
energy eigenvalues were studied using in the field of
symplectic geometry and the relativistic radial
Schrödinger equation with the expanded exponential
thermal potential (parabolic potential) representing the
strong electron-electron interaction. Electron-electron
interactions can strongly affect the effective mass, mass
spectrum, and functionality of multi-electron quantum
dots. A quanto-relativistic interaction's behavior and
effects with temperature dependence in the magnetic field
are shown to have a unique feature in semiconductor
quantum dots. These results have important implications
for lighting, quantum dot enhancement film, rational
design, edge optic, new materials, spin electronics color
filter, on-chip, visible and IR/NIR image sensor,
photovoltaic, and fabrication of quantum dot qubits with
predictable properties.
