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…
