An experimental two-dimensional semiconductor can harness the power of ambient light to serve as a "smart filter" and vastly improve the quality of photos taken with cheap cameras.
The platform, which measures 0.4 by 0.4 inch (1 by 1 centimeter), is made of a 100-by-100-pixel array that is just a few atoms thick — meaning the chip is transparent. The device was described in a study published March 18 in the journal Nature Communications.
