An international team of researchers (China, Finland) used carbon nanotubes to achieve energy spreads as low as 0.25 eV to demonstrate field-driven ultrafast photo electron emission, in a system capable of much higher phase synchronization than its photon-driven counterpart. According to the researchers, their work will help reshape our understanding of strong field physics, and may very well light the way for entirely new types of electron emission systems.
