Figure 2. A, Temperature-dependent tunneling spectra of the ZEBS induced by Fe adatoms on single-layer FeTeM0.5Se0.5 (open circles). The solid curves are the convoluted 4.2-K spectra by Fermi-Dirac distribution function at higher temperatures (both vertically offset for clarity). The inset is the atomic resolution image of Fe adatom on single-layer FeTe0.5Se0.5. B, The temperature evolution of the zero-bias conductance Gp extracted from A. C, Width analysis of ZBCPs. D,E, Fe adatom dimer and corresponding tunneling spectra. F, The ZEBS spectra at different tunneling-barrier conductances GN. G, Majorana scaling equation analysis.
