Atmospheric Oxygen Binding and Hole Doping in Deformed Graphene on a SiO2 Substrate
Sunmin Ryu, Li Liu, Stephane Berciaud +5
Using micro-Raman spectroscopy and scanning tunneling microscopy, we study the relationship between structural distortion and electrical hole doping of graphene on a silicon dioxid…
Raman Spectroscopy Study of Annealing-Induced Effects on Graphene Prepared by Micromechanical Exfoliation
Jieun Song, Taeg Yeoung Ko, Sunmin Ryu
In this note, we report a Raman spectroscopy study of annealing-induced effects on graphene samples prepared by the microexfoliation method. It was shown that randomly located adhe…
Anomalous Lattice Vibrations of Single and Few-Layer MoS2
Changgu Lee, Hugen Yan, Louis E. Brus +3
Molybdenum disulfide (MoS2) of single and few-layer thickness was exfoliated on SiO2/Si substrate and characterized by Raman spectroscopy. The number of S-Mo-S layers of the sample…
