Influence of voltmeter input impedance on quantum Hall effect measurements
F. Fischer, M. Grayson
We report on the influence of voltmeters on measurements of the longitudinal resistance in the quantum Hall effect regime. We show that for typical input resistances for standard d…

Modulating the growth conditions: Si as an acceptor in (110) GaAs for high mobility p-type heterostructures
F. Fischer, M. Grayson, D. Schuh +2
We implement metallic layers of Si-doped (110) GaAs as modulation doping in high mobility p-type heterostructures, changing to p-growth conditions for the doping layer alone. The s…

Measuring carrier density in parallel conduction layers of quantum Hall systems
M. Grayson, F. Fischer
An experimental analysis for two parallel conducting layers determines the full resistivity tensor of the parallel layer, at magnetic fields where the other layer is in the quantum…
