Notes:
3 (100)- × surfaces with ultrahigh vacuum scanning tunnel ing microscopy (UHV-STM) at room temperature. Adenine molecules migrate over the surface at a negative sample bias voltage and they are desorbed from the surface at a positive sample bias. The tip-assisted migration occurred in the two different modes, which are influenced by a high-intensity electric field and the tip-molecule contact interaction. The tip-assisted desorption was induced in a high-intensity electric field. These modes were based on quantitative measurements of the absolute tip-sample distance and of the electric field between the tip and the surface.
