The changing of electronic properties after atom trapping.

STM image of an array of open Fe corrals of diameters 7.5, 8.5, 9.8 and 10.5 nm before (a) and after (c) trapping Gd adatoms. The image sizes of (a) and (c) are 40 × 40 nm2. The dI/dU spectra are measured at the centers of different corrals before (b) and after (d) trapping Gd adatoms.
