Abstract

We present a simple method for calculating the transfer matrix of a one dimensional system consisting of a number of rectangular barriers of arbitrary shape. We also make use of the Cayley-Hamilton theorem and the spectral theory of finite complex matrices to calculate high powers of matrices in a simple way, obtaining analytic expressions that are easily evaluated. We give an example of the transmission coefficient and conduction bands for a complex-basis superlattice. The method provides an intuitive approach to the construction for the transfer matrix.
