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

PHILADELPHIA Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

Now a team of researchers from the University of Pennsylvania has shown that nanoscale particles, or nanocrystals, of the semiconductor cadmium selenide can be "printed" or "coated" on flexible plastics to form high-performance electronics.

The research was led by David Kim, a doctoral student in the Department of Materials Science and Engineering in Penn's School of Engineering and Applied Science; Yuming Lai, a doctoral student in the Engineering School's Department of Electrical and Systems Engineering; and professor Cherie Kagan, who has appointments in both departments as well as in the School of Arts and Sciences' Department of Chemistry. Benjamin Diroll, a doctoral student in chemistry, and Penn Integrates Knowledge Professor Christopher Murray of Materials Science and of Chemistry also collaborated on the research.

Their work was published in the journal Nature Communications.

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

Besides speed, another advantage cadmium selenide nanocrystals have over amorphous silicon is the temperature at which they are deposited. Whereas amorphous silicon uses a process that operates at several hundred degrees, cadmium selenide nanocrystals can be deposited at room temperature and annealed at mild temperatures, opening up the possibility of using more flexible plastic foundations.
