Inversion layers at PbTe interfaces

This is the authors' abstract. We don't add key points for this paper.

Synchrotron-radiation photoemission experiments directly demonstrate that the creation of an inversion layer is a common feature of the PbTe-Al, PbTe-In, and PbTe-Ge interface formation processes. This phenomenon is interpreted in terms of the experimentally observed adatom-Pb exchange reactions.
