From: Spectroscopic study of Gd nanostructures quantum confined in Fe corrals

TB calculated LDOS.
The results were calculated at the centers of corrals of different sizes: (a) for empty corrals, (b) for Gd occupied corrals and (c) for Gd structure after artificially removing Fe corrals. The insets show corresponding STM images for 8.5-nm corral.
