Nonlocal Transport in Cr-doped (Bi,Sb)2Te3: Absence of Nonchiral Edge States
Valery Ortiz Jimenez, Paul M. Haney, Farzad Mahfouzi +3
The quantum anomalous Hall effect shows great promise for realization of the ohm without the need for an external magnetic field. The most mature material platform is magnetically…
Novel diamagnetic garnet-type substrate single crystals for ultralow-damping yttrium iron garnet Y3Fe5O12 films at cryogenic temperatures
C. Guguschev, C. Dubs, R. Blukis +9
Y3Sc2Ga3O12-Y3Sc2Al3O12 and Y3Sc2Ga3O12-Y3Al5O12 (YSGAG) solid solution single crystals with diameters up to 30 mm and total lengths up to about 100 mm were grown by the convention…
From Wye-Delta to Cross-Square Recursion Configurations in Graphene-Based Quantum Hall Arrays
Ngoc Thanh Mai Tran, Marta Musso, Dominick S. Scaletta +8
In electrical metrology, the quantum Hall effect is accessed at the Landau level filling factor ν = 2 plateau to define and disseminate the unit of electrical resistance (ohm). Th…
Influences of the Minkowski-Bouligand Dimension on Graphene-Based Quantum Hall Array Designs
Dominick S. Scaletta, Ngoc Thanh Mai Tran, Marta Musso +7
This work elaborates on how one may develop high-resistance quantized Hall array resistance standards (QHARS) by using star-mesh transformations for element count minimization. Ref…
