Abstract :
An automated resistance bridge has been constructed specifically to measure the Hall resistance of semiconductor devices which exhibit the quantum Hall effect. The bridge is used to perform a one-to-one comparison of the Hall resistance to a reference resistor of similar value. A measurement accuracy of 0.01 ppm or better is expected.
