Atomically Thin Light-Emitting Device Could Advance 'Invisible' Displays

Facebook X LinkedIn Email
Engineers have built a bright light-emitting device that is millimeters wide and fully transparent when turned off. The light-emitting material in the device is a monolayer semiconductor that is just three atoms thick. Researchers at University of California, Berkeley used LED technology on monolayer semiconductors to create a design that can be scaled from sizes smaller than the width of a human hair up to several millimeters. The thickness of the device can be minimal but the width and length of the device can be large, so that the light intensity can be high even if the device is...Read full article

    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
