  Though significant advances have been made in the field of metal
nanostructures, researchers are yet to synthesize one atom thin two-dimensional
2D gold nanostructures. We report, for the first time, a technique to
synthesize one atom thin gold films and membrane like porous films on silicon
and sapphire. These films were essentially liquid at room temperature.
Current-Voltage spectroscopy using atomic force microscopy revealed a typical
Schottky behavior with a very high turn on (knee) voltage at 4.15V indicating
that these 2D gold structures are semi-conductors. Nanorings comprising self
assembled one atom thin gold structures on sapphire were also observed.
Subjecting one nanoring in a group of several nanorings to a point force of
2.25 micro newton for 120 seconds resulted in the creation of a mirror
structure, accompanied by every nanoring in the group to simultaneously create
its individual mirror structures. These mirror structures had an apparent
spatial and temporal correlation to each other. They had a finite life time of
a few hours and the process was repeatable to a great degree of precision.
