Penn research advances understanding of lead selenide nanowires
Date:4/8/2011

onsistent.

"You don't have to go to high temperatures to get mass quantities of these high-quality lead selenide nanowires," Kim said. "The techniques we use are high yield and high purity; we can use all of them."

And because the conductive qualities of the lead selenide nanowires can be changed while they are situated in a device, they have a wider range of functionality, unlike traditional silicon semiconductors, which must first be "doped" with other elements to make them "p" or "n."

The Penn team's work is a step toward integrating these nanomaterials in a range of electronic and optoelectronic devices, such as photo sensors.
