LEDs could turn screens into touchless chargers!
In this futuristic package, technologies are like nanorods and Light Fidelity (Li-Fi).
They produced a pixel LED of nanorods capable of emitting and detecting light.
A professor at the University of Illinois, Moonsub Shim said that Nanorods contain three different semiconductor materials.
The researchers modified small versions of LEDs, called quantum dots.
Normally, the semiconductor material isolates a quantum point inside a shell, preventing it from detecting light.
To solve this problem, scientists created the nanorods.
In this way, the quantum dots directly remain in contact with two semiconductor materials.
One allows the movement of the positive charge, and the other allows the movement of the negative charge.
Together, these materials can regulate the movement of electrons into and out of the quantum point.
