Fig. 3: Diffusion at 150 Celsius degrees.
From: Periodic corner holes on the Si(111)-7×7 surface can trap silver atoms
The set of six filled states STM images (a–f) separated by about 45 s of the same surface area (14×14 nm2, −1.0 V, 166 nA) showing diffusing one Ag atom from one corner hole to the other corner hole through HUCs at about 150 Celsius degrees. The area of interests where diffusion of single Ag atom takes place is outlined by the triangular shape and diffusing atom is denoted by the arrow. In (a) Ag atom is in the CH. In (b) the Ag atom is in FHUC and in (c) the Ag atom is in FHUC. (d) Ag is in transition between FHUC and UHUC. In (e) the Ag atom is in FHUC. In (f) the Ag atom is in CH. In all the images we can see more CHs that are occupied with Ag atoms but during this process they stay unchanged. Original files in (a–f) are provided in Supplementary Data 2: (a) m112_ori.par, m112_ori.tf0, m112_ori.tb0. (b) m113_ori.par, m113_ori.tf0, m113_ori.tb0. (c) m114_ori.par, m114_ori.tf0, m114_ori.tb0. (d) m115_ori.par, m115_ori.tf0, m115_ori.tb0. (e) m116_ori.par, m116_ori.tf0, m116_ori.tb0. (f) m120_ori.par, m120_ori.tf0, m120_ori.tb0.
