Toward full carbon interconnects: High conductivity of individual carbon nanotube to carbon nanotube regrowth junctions

A versatile chemical vapor deposition (CVD) based method for the fabrication and electrical measurement of individual carbon nanotube junctions was developed. ferritin or Fe particles were grafted on multiwalled carbon nanotubes (MWNTs) and used as catalysts for the subsequent growth of secondary MWNT by CVD. Junctions were then individually connected. The conductivities of the MWNTs and of the junction were measured. Statistical data show that the conductance of the MWNT-MWNT junction is similar to that of MWNT. This result paves the way for the use of carbon nanotubes as electrical interconnects in electronic applications.

Synthesis of Palladium Conductive DNA‐based Nanowires

We present here a simple method to metallize DNA by Electroless Plating of palladium, a trusty metal for contacting SWNT devices. Indeed, DNA is a promising scaffolding candidate for molecular electronic bottom‐up self‐assembly approaches of SWNT devices. We report in this work the synthesis and characterization of individual Pd nanowires as thin as 30 nm showing ohmic behavior at room temperature.
