A research team in Kiel has demonstrated a previously unknown effect in graphene—a single layer of carbon atoms whose discovery earned the 2010 Nobel Prize. For years, graphene has been seen as a promising material for nanoelectronics, thanks to its exceptional conductivity, flexibility, and stability. Now, researchers from the Institute of Theoretical Physics and Astrophysics at Kiel University have taken this promise a step further.
In a study published in Physical Review Research, Dr. Jan-Philip Joost and Professor Michael Bonitz show for the first time that light pulses can generate electrons at specific designated locations in the material. To investigate how electrons move and interact, they simulated the effects of laser pulses on small graphene clusters. Their results open up entirely new approaches for nanoelectronics.
