Unconventional double-bended saturation of carrier occupation in optically excited graphene due to many-particle interactions
Saturable absorption, a technologically relevant property of graphene, is usually explained with Pauli blocking of optically driven carriers in the strong-excitation regime. Here, Winzeret al. reveal a new saturation regime at low excitations, resulting in a double-bended saturation behaviour.
