Abstract
Four-terminal resistance measurements are made on GaAs-AlGaAs heterostructure Hall-bar devices with and without a cross gate. When electrons are injected from disordered contacts, anomaly is observed in both longitudinal and Hall resistances in the integer quantum Hall regime. The results are interpreted by an analysis of a contact originally developed by Buttiker.
