In this study, we investigate how the confinement shape affects the hydrogenic donor \({D}^{0}\) impurity, trapped within the quantum dot (QD). Considering the effects of Rashba and Dresselhaus spin-orbit interactions, along with an applied magnetic field, we analyze the system using the power exponential potential. We estimated the energies of the ground and first excited states using the variational approach. A systematic study of binding and transition energies was performed, exploring the effects of QD parameters and various shapes of the confinement potential. The results show transformative behaviour in response to variations in potential shape, QD characteristics, and coupling strength of the spin-orbit interaction. This study gives light on the fundamental physics of QDs and impurities, allowing for improvements in detector and sensor technology.

摘要

In this study, we investigate how the confinement shape affects the hydrogenic donor \({D}^{0}\) impurity, trapped within the quantum dot (QD). Considering the effects of Rashba and Dresselhaus spin-orbit interactions, along with an applied magnetic field, we analyze the system using the power exponential potential. We estimated the energies of the ground and first excited states using the variational approach. A systematic study of binding and transition energies was performed, exploring the effects of QD parameters and various shapes of the confinement potential. The results show transformative behaviour in response to variations in potential shape, QD characteristics, and coupling strength of the spin-orbit interaction. This study gives light on the fundamental physics of QDs and impurities, allowing for improvements in detector and sensor technology.
