Congrats to recent-PhD-grads Brittany Smith and Faris Albarghouthi on leading our latest advancement in printed, carbon-based electronics! Print processes have been limited to, at best, 10's of microns in resolution for printed features and this barrier was shattered by the use of a capillary flow printing technique that allowed for the direct printing of thin-film transistors with channel lengths only a few hundred nanometers in size. The work is reported in the journal Nature Electronics and is receiving media attention (see below)!
