Collinear scattering of photoexcited carriers in graphene

Understand

We propose an explicitly solvable model for collinear scattering of photoexcited carriers in intrinsic graphene irradiated by monochromatic light.

• We find that the collinear scattering rate is directly proportional to the photocarrier energy and derive an analytic expression for the corresponding relaxation time.
• The result agrees with the recent numerical prediction [Mihnev et al.
• Nat.
