We have shown that the self-polarization and binding energy of a hydrogenic impurity in a tetragonal quantum dot depends strongly on the theta angle of the spatial electric field, the size effect (L-z/L ratio (M)), the volume of the dot, and impurity position. Furthermore, we define the angle theta(max), which aligns the spatial electric field vector with the position vector of the hydrogenic impurity on the diagonal axis. It has been noted that self-polarization reaches its peak at this particular angle.en10.1007/s12648-023-03017-yinfo:eu-repo/semantics/closedAccessQuantum DotHydrogenic ImpuritySelf-PolarizationBinding EnergySpatial Electric FieldConduction-Band NonparabolicityHydrogenic Donor ImpurityBinding-EnergyHydrostatic-PressureWellTemperaturePolarizabilityStatesMassArticle98723752382N/AWOS:0011418881000012-s2.0-85182190236Q3
