Variability Effects in Graphene: Challenges and Opportunities for Device Engineering and Applications
Guangyu Xu, Yuegang Zhang, Xiangfeng Duan +2
Variability effects in graphene can result from the surrounding environment and the graphene material itself, which form a critical issue in examining the feasibility of graphene d…
Edge effect on resistance scaling rules in graphene nanostructures
Guangyu Xu, Carlos M. Torres, Jianshi Tang +6
We report an experimental investigation of the edge effect on the room-temperature transport in graphene nanoribbon and graphene sheet (both single-layer and bilayer). By measuring…
Enhanced Conductance Fluctuation by Quantum Confinement Effect in Graphene Nanoribbons
Guangyu Xu, Carlos M. Torres, Emil B. Song +5
Conductance fluctuation is usually unavoidable in graphene nanoribbons (GNR) due to the presence of disorder along its edges. By measuring the low-frequency noise in GNR devices, w…
Effect of Spatial Charge Inhomogeneity on 1/f Noise Behavior in Graphene
Guangyu Xu, Carlos M. Torres, Yuegang Zhang +6
Scattering mechanisms in graphene are critical to understanding the limits of signal-to-noise-ratios of unsuspended graphene devices. Here we present the four-probe low frequency n…
