Confocal laser scanning microscopy: A tool for rapid optical characterization of 2D materials
Vishal Panchal, Yanfei Yang, Guangjun Cheng +9
Confocal laser scanning microscopy (CLSM) is a non-destructive, highly-efficient optical characterization method for large-area analysis of graphene on different substrates, which…
Rapid characterization of wafer-scale 2D material: Epitaxial graphene and graphene nanoribbons on SiC
Vishal Panchal, Yanfei Yang, Guangjun Cheng +8
We demonstrate that the confocal laser scanning microscopy (CLSM) provides a non-destructive, highly-efficient characterization method for large-area epitaxial graphene and graphen…
Epitaxial graphene homogeneity and quantum Hall effect in millimeter-scale devices
Yanfei Yang, Guangjun Cheng, Patrick Mende +8
Quantized magnetotransport is observed in 5.6 x 5.6 mm^2 epitaxial graphene devices, grown using highly constrained sublimation on the Si-face of SiC(0001) at high temperature (190…
UV/Ozone treatment to reduce metal-graphene contact resistance
Wei Li, Yiran Liang, Dangmin Yu +10
We report reduced contact resistance of single-layer graphene devices by using ultraviolet ozone (UVO) treatment to modify the metal/graphene contact interface. The devices were fa…
