Numerical Solution of One-Dimensional Stationary Schr?dinger Equation in the Frequency Domain

摘要

1.1 Introduction Recently, quantum wells on base of semiconductor heterostructures are most widely studied [1] since their physical effects can be seen at room temperature [2] and can be applied in actual devices, for example, as some components of optoelectronic devices such as photodetectors in infrared spectral range [3], quantum cascade lasers [4], and other optoelectronic devices [5]. A detailed theory of optoelectronic devices based on quantum wells can be found in the book by G. Bastard in [6].
