Microcavities save organic semiconductors from going dark

Researchers found a way to keep these organic semiconductors from going dark. They used tiny sandwich structures of mirrors, called microcavities, to trap light and force it to interact with a layer of molecules, forming a new hybrid state, known as a polariton, that mixes light and matter.This approach could lead to brighter, more efficient LEDs, sensors and solar cells.

A new view for glasses

Scientists used computer simulations to demonstrate how the dynamics of a glassy liquid can be predicted based on the local structural ordering at the atomic level. This work may lead to a deeper understanding of glass transition.
