In this paper, we investigate the influence of methods of fabricating the structure and geometry of a sample of a topological insulator on transport in it. The idea of spin polarization of the electric current passing through the sample by lengthening one of the two edges is proposed, and the results of measurements of the local and nonlocal conductivity of a structure with a similar geometry are described. The idea of spin polarization of the electric current passing through the sample by creating densely spaced holes along one of the edges, as well as ideas for the implementation of such an array of holes are proposed.
