Rice researchers discover that a simple filtration technique produces wafer-scale films of highly aligned carbon nanotubes. The thin films offer possibilities for flexible electronic and photonic devices.
A simple filtration process helped Rice University researchers create flexible, wafer-scale films of highly aligned and closely packed carbon nanotubes. In the right solution of nanotubes and under the right conditions, the tubes assemble themselves by the millions into long rows that are aligned better than once thought possible, the researchers reported.
