Using quantum dots offers alternative to traditional semiconductor devices.

Anne L. Fischer

Because of their use in digital cameras and in night-vision and security systems — all growing markets — and in fiber optic communications, photodetectors are in hot demand. It’s no wonder that researchers are looking for ways to simplify the process by which they are produced. A group at the University of Toronto has developed a manufacturing process that paints a solution of quantum dots onto gold electrodes. Painting a liquid containing quantum dots onto gold electrodes has simplified the process of developing photodetectors. The investigators placed gold electrodes on a glass slide...Read full article
