Self-assembled CNT circuits with ohmic contacts using Pd hexadecanethiolate as in situ solder

Thiruvelu Bhuvana, Kyle C. Smith, Timothy S. Fisher and Giridhar U. Kulkarni

An easy and elegant method of CNT nanocircuit fabrication using a metal organic precursor of Pd, namely, Pd hexadecanethiolate, is presented. This precursor directs the self-assembly of individual CNTs spanning a gap between Au electrodes. This is achieved by first patterning the precursor along the edges of the gap electrodes, as it enables direct patterning by e beam. Further, thermal activation of the precursor at 250 °C leads to metallization and the ohmic electrical contact between the CNTs and the electrodes beneath. A resistive fuse action of the soldered CNTs is observed as well.
