University of Pennsylvania researchers have shown that nanocrystals of the semiconductor cadmium selenide can be “printed” or “coated” on flexible plastics to form high-performance electronics.
Electronic circuits are typically integrated in rigid silicon wafers. Flexibility opens up a wide range of applications, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

“We have a performance benchmark in amorphous silicon, which is the material that runs the display in your laptop, among other devices,” said professor Cherie Kagan.
“Here, we show that these cadmium selenide nanocrystal devices can move electrons 22 times faster than in amorphous silicon.”
