New Additive Offers Near-Perfect Results as Nucleating Agent for Organic Semiconductors

June 11, 2013

Researchers at UC Santa Barbara develop a new method of controlling crystallization of organic semiconductors and increasing the yield of devices to nearly 100 percent using a low-cost, sugar-based additive

Pixie dust may be the stuff of fanciful fiction, but for scientists at UC Santa Barbara’s Department of Materials, a commonly used sugar-based additive has been found to have properties that are near magical. By adding minute amounts of it during the fabrication of organic semiconductors, they have been able to dramatically increase yield and control crystallization, which could, in the near future, make the technology not only cheaper and more accessible, but also enhance its performance. Results of their study are published in the recent issue of the journal Nature Materials.
