| dc.description.abstract | We have measured carrier relaxation times and nonlinear optical properties in three functionalized epitaxial graphene layers grown on SiC wafers by using ultrafast optical pump-probe spectroscopy and open aperture z-scan at 780 nm. The results demonstrate that after different functionalization, the ratios of the slower relaxation in the range of 3.1-4.6 ps (related to carrier-phonon intraband and interband scattering) increase about 2-6 times compared to original graphene. These changes of relaxation obviously improved the nonlinear optical properties, making functionalized epitaxial graphene can be used as a tuneable saturable absorber. © 2012 Published by Elsevier Ltd. | |
