Abstrakt: An experimental study is performed of the differences between the electronic states necessarily formed at the boundaries of a topological phase in a vacuum and a trivial buffer in the regions of heterojunction in topological materials based on Hg1 –xCdxTe epitaxial films. It is shown that the PT-symmetric terahertz photoconductivity observed in the specified structures is due precisely to states in the region of topological film/trivial buffer (or cap layer) interfaces.
