Promising Materials Emerge for Next-Gen LED-Based Data Communications

Facebook X LinkedIn Email
A team of researchers has examined how organic semiconductors, colloidal quantum dots (CQDs), and metal halide perovskites can be used in high-speed LED-based optical communication systems. LED-based techniques enable computing devices to communicate with one another by using infrared light. However, LED techniques aren’t often used. In their current state, LEDs transmit data at far slower speeds compared to other wireless technologies such as light-fidelity (Li-Fi). The team explored efforts to improve the performance and efficiency of these LEDs with consideration of their...Read full article

    perovskite
    The term perovskite refers to a specific crystal structure commonly found in various materials. Perovskite structures have a cubic arrangement of oxygen ions, forming a framework within which other cations (positively charged ions) are located. This crystal structure was named after the mineral perovskite, which has the chemical formula CaTiO3 and was first discovered in the Ural Mountains of Russia. The general formula for the perovskite structure is ABX3, where: A represents a larger...
