Hot phonon decay in supported and suspended exfoliated graphene
P. J. Hale, S. M. Hornett, J. Moger +2
Near infrared pump-probe spectroscopy has been used to measure the ultrafast dynamics of photoexcited charge carriers in monolayer and multilayer graphene. We observe two decay pro…

Strong nonlinear optical response of graphene flakes measured by four-wave mixing
E. Hendry, P. J. Hale, J. J. Moger +2
We present the first experimental investigation of nonlinear optical properties of graphene flakes. We find that at near infrared frequencies a graphene monolayer exhibits a remark…
