The best poster ECOSS-31

 Jan Berger presented a poster entitled "" which received the Poster award in 31-th ECOSS conference held in Barcelona, Septemeber 2015. Atomic manipulation of the delta-doped B:Si(111) surface was carried out using the Kolibri sensor based low temperature nc-AFM. To create a vacancy, a Si adatom was removed via a controlled vertical displacement of the probe. We succeeded to close the vacancy site by precisely placing a Si atom back, thus demonstrating that this process is completely reversible. During the manipulations, the rearrangement of atoms at the tip apex occurs, leading to a sharpening of the tip. This enables us to look deeper inside the vacancy. It appeared that the removal of a Si adatom exposes subsurface Si dangling bond (DB) triplets, surrounding the B dopant in the first bilayer. DFT calculations reproduced nicely the experimental results and suggest, that the tip is likely terminated by two Si atoms at the tip apex. Moreover, it is shown that the closing of the vacancy was possible only when atomic manipulation was performed with the tip placed off-center the vacancy site. The content of the poster was published in Small journal.
