Ad-atom configurations under consideration.

The distance d between the ad-atom(s) and the chain is varied. The t-parameters refer to the tight-binding description of the central scattering region; see main text. The impurity configurations studied, (a)–(d), are denoted A–D, respectively, in the main text for clarity.
