CLF Highlight: Artemis Laser’s High-Speed Measurement Capabilities Used to Study Intriguing 2D Material
In 2013, the first direct measurements of ultrafast electronic dynamics in graphene – recognised as the world’s first 2D material – were made using Artemis. The resulting papers now have over 1,000 citations between them:
