Abstract
Bi Doped Graphene In article number 2206218, Xianyang Lu, Thomas Frauenheim, Yongbing Xu, and co-workers investigate femtosecond laser excitation induced electronic dynamic in Bi doped graphene, using time resolved and angular resolved photoemission spectrum. The Fermi surface in Dirac cone and carrier concentration is modulated by adatoms' content. This effectively tailors the competition between auger combination and impact excitation, tuning the carrier multiplication in graphene.
