Room temperature deposition of 2-dimensional single-walled carbon nanotube (SWNT) networks
MetadataShow full item record
The work presented herein develops a new understanding of a novel deposition method for formation of single-walled carbon nanotube (SWNT) networks at room-temperature. Due to their nanometer scale dimensions, ability to exhibit either semiconductive or metallic conduction, compatibility with flexible substrates and extreme sensitivity to surface adsorption events, there is great interest in understanding and harnessing the enhanced properties of SWNT networks in a wide variety of electronic device structures; possible applications vary from lightweight/flexible electronics, energy conversion, sensing and catalysis. A major advantage of the SWNT network deposition method studied herein is that it decouples the network deposition (which occurs at roomtemperature) from the SWNT growth process (which occurs at 800o C), allowing intermediate purification and modification steps. Further, it will be demonstrated that SWNT networks of arbitrary density and alignment may be formed.
