【Abstract】 The quasi-bound levels in biased/unbiased double/triple-barrier quantum structures have been exactly calculated based on the solution of the one-)dimensional (1D) time-independent Schrdinger equation using Airy function and transfer matrix method, which is easily extended to multi-barrier quantum structures; furthermore, the dependence of the quasi-bound levels on the effective masses and bias in biased/unbiased double/triple-barrier quantum structures has also been investigated. In addition, errors of Airy function and transfer matrix method in the study of quasi-bound levels of biased multi-barrier quantum structures in other letters have been pointed out and verified.更多还原
