Abstract

We report selective lateral nano-bridging of carbon nanowire (CNW) between microsized islands using conventional photolithography technique necessary for the nanomachining and the molecular device applications compatible with Si-based process. Most distinct feature in this work is to use a growth barrier of Nb metal or insulating layer on the top of the catalytic Ni metal to prevent the growth of CNW from vertical direction to the substrate. As a result, CNWs of either "straight line" or a "Y-junction" were selectively grown between lateral sides of the catalytic metals or pre-defined electrodes without any trace of vertical growth. These results clearly indicate that this method would be one of the most feasible fabrication techniques for the nanomachines or the electronic applications with high integration level through process optimization.
