Spatially resolved pump-probe study of single-layer graphene produced by chemical vapor deposition
Brian A. Ruzicka, Shui Wang, Jianwei Liu +3
Carrier dynamics in single-layer graphene grown by chemical vapor deposition (CVD) is studied using spatially and temporally resolved pump-probe spectroscopy by measuring both diff…
Two-probe study of hot carriers in reduced graphene oxide
Brian A. Ruzicka, Nardeep Kumar, Shuai Wang +2
The energy relaxation of carriers in reduced graphene oxide thin films is studied using optical pump-probe spectroscopy with two probes of different colors. We measure the time dif…
Hot carrier diffusion in graphene
Brian A. Ruzicka, Shuai Wang, Lalani K. Werake +3
We report an optical study of charge transport in graphene. Diffusion of hot carriers in epitaxial graphene and reduced graphene oxide samples are studied using an ultrafast pump-p…
Femtosecond Pump-Probe Studies of Reduced Graphene Oxide Thin Films
Brian A. Ruzicka, Lalani K. Werake, Hui Zhao +2
The dynamics of photocarriers in reduced graphene oxide thin films is studied by using ultrafast pump-probe spectroscopy. Time dependent differential transmissions are measured wit…
