Abstract

The nanoscale deposition of solid organic 'ink' was investigated using thermal dip pen nanolithography (tDPN). The deposition occurs only when the cantilver tip is heated above melting temperature of octadecylphosphonic acid (OPA) such that deposited structure does not spread significantly while cooling, which was revealed by postdeposition analysis. The single lines were found to be written with a width of 100 nm. The results show that tDPN allows local control of deposition and deposition of materials typically immobile at room temperature.
