Slow-motion electron camera reveals light-driven quantum jumps in graphene

Physicists from Regensburg, Marburg and Jülich used a new slow-motion electron camera to show how intense electric fields drive electrons in graphene to jump across energy gaps. The approach combines laser technology with electron microscopy.
