  • Hot phonon decay in supported and suspended exfoliated graphene 

    Hale, Peter J.; Hornett, Samuel M.; Moger, Julian; Horsell, D.W.; Hendry, Euan (American Physical Society, 2011-03-14)
    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 processes occurring on 100 fs and 2 ps ...
  • Nonlinear resistivity and heat dissipation in monolayer graphene 

    Price, A.S.; Hornett, Samuel M.; Shytov, A.V.; Hendry, Euan; Horsell, D.W. (American Physical Society, 2012)
    We have experimentally studied the nonlinear nature of electrical conduction in monolayer graphene devices on silica substrates. This nonlinearity manifests itself as a nonmonotonic dependence of the differential resistance ...
  • Optically induced oxygen desorption from graphene measured using femtosecond two-pulse correlation 

    Hornett, Samuel M.; Heath, M.; Horsell, D.W.; Hendry, Euan (American Physical Society, 2014)
    Recently, there has been a great deal of interest in the effect of atmospheric gases on the properties of graphene. We investigate the electrical and optical response of graphene-based field effect transistors that have ...
