Visualizing Individual Nitrogen Dopants in Monolayer Graphene
Liuyan Zhao, Rui He, Kwang Taeg Rim +15
In monolayer graphene, substitutional doping during growth can be used to alter its electronic properties. We used scanning tunneling microscopy (STM), Raman spectroscopy, x-ray sp…
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…
The Atomic-scale Growth of Large-Area Monolayer Graphene on Single-Crystal Copper Substrates
L. Zhao, K. T. Rim, H. Zhou +5
We study the growth and microscopic structure of large-area graphene monolayers, grown on copper single crystals by chemical vapor deposition (CVD) in ultra-high vacuum (UHV). Usin…
Graphene Oxidation: Thickness Dependent Etching and Strong Chemical Doping
Li Liu, Sunmin Ryu, Michelle R. Tomasik +6
Patterned graphene shows substantial potential for applications in future molecular-scale integrated electronics. Environmental effects are a critical issue in a single layer mater…
High-Resolution Scanning Tunneling Microscopy Imaging of Mesoscopic Graphene Sheets on an Insulating Surface
Elena Stolyarova, Kwang Taeg Rim, Sunmin Ryu +6
We present scanning tunneling microscopy (STM) images of single-layer graphene crystals examined under ultrahigh vacuum conditions. The samples, with lateral dimensions on the micr…
