Abstract

A dispersion containing 15nm gold particles in ethanol was subjected to electrohydrodynamic atomization, producing droplets with an average size of similar to 26 mu m as measured by laser diffraction. An electrohydrodynamic direct-write device was used to deposit the dispersion onto silicon wafers with the intention of printing gold tracks. Immediately after deposition ethanol evaporated, leaving the gold particles organised in a similar to 75 mu m wide central region surrounded by two regions, each similar to 50 mu m wide, at the edge of which two further gold tracks, each similar to 7 mu m existed.
