Variable Electrical Responses in Epitaxial Graphene Nanoribbons
C. -C. Yeh, S. M. Mhatre, N. T. M. Tran +7
We have demonstrated the fabrication of both armchair and zigzag epitaxial graphene nanoribbon (GNR) devices on 4H-SiC using a polymer-assisted sublimation growth method. The pheno…
Spectroscopic assessment of short-term nitric acid doping of epitaxial graphene
Ngoc Thanh Mai Tran, Swapnil M. Mhatre, Cristiane N. Santos +10
This work reports information on the transience of hole doping in epitaxial graphene devices when nitric acid is used as an adsorbent. Under vacuum conditions, desorption processes…
Timescales for Nitric Acid Desorption in Epitaxial Graphene Devices
Swapnil M. Mhatre, Ngoc Thanh Mai Tran, Heather M. Hill +6
This work reports the dynamics of transient hole doping in epitaxial graphene devices by using nitric acid as an adsorbent. The timescales associated with corresponding desorption…
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…
Fabrication of quantum Hall p-n junction checkerboards
Dinesh K. Patel, Martina Marzano, Chieh-I Liu +4
Measurements of fractional multiples of the ν=2 plateau quantized Hall resistance (R_H {\approx} 12906 Ω) were enabled by the utilization of multiple current terminals on millimetr…
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…
