This article reports a theoretical study of the intersubband optical properties in quantum wells with modified Manning potential considering the effects of position-dependent effective mass. Calculations are made in the effective mass and parabolic band approximations. The electronic spectrum, dipole matrix element for intersubband transitions, optical absorption coefficient, and refractive index coefficient are reported. Modifying the Manning potential’s three parameters is a useful tool to simulate single and multiple quantum wells. The solution of the eigenvalues differential equation is implemented through the expansion technique based on orthonormal trigonometric functions. Such a procedure is contrasted with those obtained from solving the problem by using the finite element method. Both methods of solving the differential equations report results with excellent agreement between them and the possibility of achieving the desired precision in the spectrum energy and the wave functions and the calculated observable. The results presented here are useful for studying isolated and multiple quantum wells where interdiffusion effects are involved in the interfaces. The findings demonstrate the versatility of the modified Manning potential since, by properly manipulating its three parameters, it is possible to tune the spectrum of energies with potential applications in next-generation optoelectronic devices.

本文报告了考虑位置相关有效质量影响的具有修正曼宁势的量子阱中子带间光学特性的理论研究。在有效质量和抛物线带近似中进行计算。报告了电子光谱、子带间跃迁的偶极矩阵元素、光吸收系数和折射率系数。修改曼宁势的三个参数是模拟单个和多个量子阱的有用工具。特征值微分方程的求解是通过基于正交三角函数的展开技术实现的。这样的过程与通过使用有限元方法解决问题所获得的过程形成对比。两种求解微分方程的方法报告的结果都非常一致，并且有可能在频谱能量和波函数以及计算的可观测量中实现所需的精度。此处介绍的结果对于研究界面中涉及互扩散效应的隔离和多量子阱很有用。研究结果证明了修改后的曼宁电位的多功能性，因为通过适当操纵其三个参数，可以调整能量谱，并在下一代光电设备中具有潜在应用。此处介绍的结果对于研究界面中涉及互扩散效应的隔离和多量子阱很有用。研究结果证明了修改后的曼宁电位的多功能性，因为通过适当操纵其三个参数，可以调整能量谱，并在下一代光电设备中具有潜在应用。此处介绍的结果对于研究界面中涉及互扩散效应的隔离和多量子阱很有用。研究结果证明了修改后的曼宁电位的多功能性，因为通过适当操纵其三个参数，可以调整能量谱，并在下一代光电设备中具有潜在应用。
