Large-scale five- and seven-junction epitaxial graphene devices
Dinesh Patel, Martina Marzano, Chieh-I Liu +8
The utilization of multiple current terminals on millimeter-scale graphene p-n junction devices has enabled the measurement of many atypical, fractional multiples of the quantized…
Nonconventional Quantized Hall Resistances Obtained with Equilibration in Epitaxial Graphene Junctions
Albert F. Rigosi, Dinesh Patel, Martina Marzano +9
We have demonstrated the millimeter-scale fabrication of monolayer epitaxial graphene junction devices using simple ultraviolet photolithography, thereby significantly reduci…
Designs for programmable quantum resistance standards based on epitaxial graphene p-n junctions
Jiuning Hu, Albert F. Rigosi, Mattias Kruskopf +13
We report the fabrication and measurement of top gated epitaxial graphene p-n junctions where exfoliated hexagonal boron nitride (h-BN) is used as the gate dielectric. The four-ter…
Chiral transport of hot carriers in graphene in the quantum Hall regime
Bin Cao, Tobias Grass, Olivier Gazzano +12
Photocurrent (PC) measurements can reveal the relaxation dynamics of photo-excited hot carriers beyond the linear response of conventional transport experiments, a regime important…
Observation of chiral photocurrent transport in the quantum Hall regime in graphene
Olivier Gazzano, Bin Cao, Jiuning Hu +6
Optical excitation provides a powerful tool to investigate non-equilibrium physics in quantum Hall systems. Moreover, the length scale associated with photo-excited charge carries…
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…
