Atomic layer graphene as saturable absorber for ultrafast pulsed lasers
Qiaoliang Bao, Han Zhang, Yu Wang +5
The optical conductance of monolayer graphene is defined solely by the fine structure constant. The absorbance has been predicted to be independent of frequency. In principle, the…
Fabrication of graphene nanodisk arrays using nanosphere lithography
C. X. Cong, T. Yu, Z. H. Ni +3
Ordered graphene nanodisk arrays have been successfully fabricated by combining nanosphere lithography (NSL) and reactive ion etching (RIE) processes. The dimension of graphene nan…
Probing charged impurities in suspended graphene using Raman spectroscopy
Zhen Hua Ni, Ting Yu, Zhi Qiang Luo +6
Charged impurity (CI) scattering is one of the dominant factors that affect the carrier mobility in graphene. In this paper, we use Raman spectroscopy to probe the charged impuriti…
Reduction of Fermi velocity in folded graphene observed by resonance Raman spectroscopy
Zhenhua Ni, Yingying Wang, Ting Yu +2
The 1+1 layer folded graphene sheets that deviate from AB stacking are successfully fabricated and their electronic structures are investigated by Raman spectroscopy. Significant b…
Raman spectroscopy of epitaxial graphene on a SiC substrate
