Schematic drawings of the normal reflection and Andreev reflection processes that contribute to the formation and energy of ABSs in the bare section (N) of the TINW. Electron transfer from Pt/Au and from Nb causes the TINW sections beneath them (N' and S', respectively) to have different mu values, resulting in normal reflection at both interfaces to the N section, as well as Andreev reflection at the NS' interface.
