ABSTRACT
Focuses on a study which discussed the effects of practical properties of gallium arsenide-aluminum gallium arsenide heterostructures on the accuracy of a quantum-Hall resistance standard. Methods of conduction that were addressed; Details of the measurement concerning the influences of sample size and mobility; Aspects of mobility that were investigated; Recommendations on sample geometry and mobility.
