Algorithms for determining resistances in quantum Hall annuli with p-n junctions
Chieh-I Liu, Dominick S. Scaletta, Dinesh K. Patel +4
Just a few of the promising applications of graphene Corbino pnJ devices include two-dimensional Dirac fermion microscopes, custom programmable quantized resistors, and mesoscopic…
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…
Quantum Hall Junction Dartboards Using Graphene Annuli
