Figure 5
Energy dependence of the scanned image of the tip current (50 nm × 50 nm, −2 V, 0.5 nA for all figures). Topographic (left) and beam-induced tip-current images (right) were simultaneously obtained at higher [(a), 11.114 keV] and lower [(b), 11.090 keV] energies than the Ge absorption edge shown in Fig. 4. |
