Using perovskite to make LED pixels as small as a virus

A team of physicists, engineers, opticians and photonics specialists at Zhejiang University, in China, working with a pair of colleagues from the University of Cambridge, in the U.K., has found a way to make pixels smaller by using perovskite. In their paper published in the journal Nature, the group describes how they used the mineral to create pixels as small as a virus.
