FIG. 1.

(Color online) [(a)–(d)] Series of STM images showing the nanostructures fabricated by STM manipulation. The Pb coverage is ML. The images were recorded at a tunneling current of and a tip bias voltage of . (a) Original Pb island before STM manipulation. (b) The center-half-hollowed nanowell formed by charging at the Pb island edge. (c) Center-full-hollowed nanowell formed by charging at the bottom of the well in (b). (d) Center-full-hollowed nanostructure with the different ratios of inner/outer diameter and thickness from the one shown in (c). (e) The cross-section profiles along the horizontal center lines in (a)–(d), respectively. (f) Dependence of the triggered growth height on the pulse amplitude.

FIG. 2.

(Color online) Schematic drawing of the STM manipulation process. The white arrows [(a)–(f)] show the process of fabricating flattop Pb island with different thicknesses. The black arrows [(a)–(i)] show the fabrication of hollow-centered nanostructures with different inner diameters and thicknesses.

Image of FIG. 3.
FIG. 3.

(Color online) STM images showing fabrication of nanoarchitecture by the manipulation. (a) Initial Pb(111) island archipelago obtained by depositing Pb atoms on the Si(111) surface. The arrows indicate the selected Pb islands to be manipulated. (b) The character “M” written by growing five preselected Pb islands and erasing all others in (a) using STM. The elapsed time from (a) to (b) is .
