To @GroovyGeek: I am not sure why you would blame EE TImes for this? Clearly this is a controversial issue that requires further science, experiments or measurements. Any new material, like carbon nanotube, will take years of development (I work on a compound material that was discovered 50 years ago, we are still perfecting it). EE Times is not Bell Labs ;-)...Kris

And a bad data point at that. I attended the talk and it was devoid of any serious analysis. The problem was mostly with electromigration of their Au electrodes (duh!). When they did observe "something" with the CNTs they made no effort to do a physical analysis to determine what is going on. It is really disappointing to see the EE Times not do their homework and highlight such low quality research.

Agree, this is hardly news since the interface is always a challenge whenever you try to bridge two materials together. Adding a graphite or graphene layer between the CNT and the metal may help to spread out the current.

NIST measures things. This is only one data point on carbon nanotube devices, too early to tell if it is a crucial one, methinks.

Of course the metal was supposed to be the weak link. That was the origin of proposing CNT as alternative to metal.
