Abstract

In this paper, we employed numerical modeling to investigate the influence of crucial parameters, namely electric field, confinement parabolicity, compositions, and structure parameters, on the electron probability, impurity polarizability, diamagnetic susceptibility, and ionization energy of hydrogenic donor impurities within a modified ∩-shaped potential. The Schrödinger equation is solved using the finite element approach within the framework of the effective mass theory to analyze the resulting electronic properties. Our results demonstrate a significant impact of these factors on both electrons and impurities, with the ability to fine-tune these properties through parameter adjustments. These findings hold significant implications for the advancement of precise and efficient III-nitride-based optoelectronic devices, including solar cells, photodetectors, and lasers.
