Abstract :
Produces a series of quantised Hall resistors suitable for high precision measurements in fields below 9 tesla. Critical currents on both steps are in excess of 100 /spl mu/A.We have optimised the structure and treatment ofthe AuGeNi contacts to give four-probe contact resistance values of 2 m/spl omega/. These contact resistance values are amongst the lowest reported.
