Quantum Dots Aim to Be Smart Pixels

Facebook X LinkedIn Email
Dr. James P. Smith

Scientists at the University of California reported the development of a “smart pixel” device based on quantum dots that can collect, store and retrieve optical information in a single efficient unit. Optical information processing typically requires three technologies: a CCD that collects the image or pattern; a computer that stores and interprets the digital output of the detector; and LEDs in a display that convert the signal back into visual information. The researchers fabricated the smart pixels by molecular beam epitaxy. They inserted an InAs layer of...Read full article
