Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny and interact strongly with each other, but move slowly. Together, the two ...

A research team in Kiel has demonstrated a previously unknown effect in graphene—a single layer of carbon atoms whose ...

For the first time, researchers show light pulses can create electrons at specific sites in graphene, uncovered through ...

Whether in solar cells or in the human eye: whenever certain molecules absorb light, the electrons within them shift from their ground state into a higher energy, excited state. This results in the ...
