NIST uncovers reliability issues for carbon nanotubes in future electronics
Date:8/18/2011

Carbon nanotubes offer big promise in a small package. For instance, these tiny cylinders of carbon molecules theoretically can carry 1,000 times more electric current than a metal conductor of the same size. It's easy to imagine carbon nanotubes replacing copper wiring in future nanoscale electronics.

Butnot so fast. Recent tests at the National Institute of Standards and Technology (NIST) suggest device reliability is a major issue.

Copper wires transport power and other signals among all the parts of integrated circuits; even one failed conductor can cause chip failure. As a rough comparison, NIST researchers fabricated and tested numerous nanotube interconnects between metal electrodes. NIST test results, described at a conference this week,* show that nanotubes can sustain extremely high current densities (tens to hundreds of times larger than that in a typical semiconductor circuit) for several hours but slowly degrade under constant current. Of greater concern, the metal electrodes failthe edges recede and clumpwhen currents rise above a certain threshold. The circuits failed in about 40 hours.

While many researchers around the world are studying nanotube fabrication and properties, the NIST work offers an early look at how these materials may behave in real electronic devices over the long term. To support industrial applications of these novel materials, NIST is developing measurement and test techniques and studying a variety of nanotube structures, zeroing in on what happens at the intersections of nanotubes and metals and between different nanotubes. "The common link is that we really need to study the interfaces," says Mark Strus, a NIST postdoctoral researcher.

In another, related study published recently,** NIST researchers identified failures in carbon nanotube networksmaterials in which electrons physically hop from tube to tube. Failures in this case seemed to occur between nanotubes, the point of highes
