“…23 Besides exactness, another advantage of the present formalism is that it is not just computing the values of T, but the entire wave function instead. Hence, for more complex potential barriers, as those usually find in heterostructures and nanodevices where resonance can take place inside the barries, 17,22,24,25 amplitudes and evanescence times of resonant modes are simultaneously computed.…”

A revision of the recursive method proposed by S.A. Shakir [Am. J. Phys. 52, 845 (1984)] to solve bound eigenvalues of the Schrödinger equation is presented. Equations are further simplified and generalized for computing wave functions of any given one-dimensional potential, providing accurate solutions not only for bound states but also for scattering and resonant states, as demonstrated here for a few examples. Keywords: one-dimensional quantum potentials, numerical solutions, computational methods, Schrödinger equation.Uma revisão do método recursivo proposto por S.A. Shakir [Am. J. Phys. 52, 845 (1984)] para solucionar autovalores de estados ligados da equação de Schrödingeré apresentado. As equações são ainda mais simplificadas e generalizadas para computar funções de onda em qualquer potencial unidimensional, fornecendo soluções acuradas não somente para estados ligados mas também para problemas de espalhamento e ressonância, como demonstrado aqui em alguns exemplos. Palavras-chave: potenciais quânticos unidimensionais, soluções numéricas, métodos computacionais, equação de Schrödinger.

“…Tunable n-i-p-i structures are attractive for integration with different optoelectronic devices, such as photoelectric detectors [4], quantum cascade lasers [5], or photonic crystal heterostructures [6]. Besides, -doped superlattices provide effective operation parameters and extent functional characteristics of photodetectors [7], modulators [8][9][10], and nonlinear optical switches [11][12][13].…”

The GaAs short-period superlattices have been grown for the first time by the metal-organic hydride epitaxy method using Se and C for quasi-doping. Photoluminescence spectra measured at 4.2 K display well-distinguished peaks, which coincide with transitions between quantizied levels of electrons and holes in the potential relief quantum wells. To describe observed phenomena in quasi-doped superlattices a theory is developed with taking into account existing tails of the density of states.
