Self-Aligned Formation of Sub 1 nm Gaps Utilizing Electromigration during Metal Deposition
We
developed a procedure for the fabrication of sub 1 nm gap Au electrodes
via electromigration. Self-aligned nanogap formation was achieved
by applying a bias voltage, which causes electromigration during metal
evaporation. We also demonstrated the application of this method for
the formation of nanogaps as small as 1 nm in width, and we found
that the gap size can be controlled by changing the magnitude of the
applied voltage. On the basis of the electric conductance and surface-enhanced
Raman scattering (SERS) measurements, the fabricated gap size was
estimated to be nearly equal to the molecular length of 1,4-benzenedithiol
(BDT). Compared with existing electromigration methods, the new method
provides two advantages: the process currents are clearly suppressed
and parallel or large area production is possible. This simple method
for the fabrication of a sub 1 nm gap electrode is useful for single-molecule-sized
electronics and opens the door to future research on integrated sub
1 nm sized nanogap devices
