Penn researchers make flexible, low-voltage circuits using nanocrystals
Date:11/26/2012

in analog circuits, and ring oscillators, where 'on' and 'off' signals are properly propagating over multiple stages in digital circuits."

"And all of these circuits operate with a couple of volts," Kagan said. "If you want electronics for portable devices that are going to work with batteries, they have to operate at low voltage or they won't be useful."

With the combination of flexibility, relatively simple fabrication processes and low power requirements, these cadmium selenide nanocrystal circuits could pave the way for new kinds of devices and pervasive sensors, which could have biomedical or security applications.

"This research also opens up the possibility of using other kinds of nanocrystals, as we've shown the materials aspect is not a limitation any more," Kim said.
