Notes:
With the present interest in nanostructures, such as quantum dots, there is a need to have a flexible method with which to be able to determine eigenvalues and eigenstates for those structures that do not lend themselves to existing analytical methods. In this article we present a method that accomplishes this by using a simulation of the Schrödinger equation based on the finite-difference time-domain method. This method is capable of simulating any structure within the limits of discretization. By initializing a simulation with a test function, the eigenfrequencies are determined through a Fourier transform of the resulting time-domain data collected at a sample point. Another simulation implements a discrete Fourier transform at the eigenfrequencies at every cell in the problem space, from which the eigenfunctions can be constructed. © 2002 American Institute of Physics.
