  • Abstract
    GaAs/GaAlAs heterostructure-based quantum Hall samples with a wide range of electron mobilities have been produced using ion implantation. The purpose was to optimize the samples for use in metrology. In particular, the critical current and the nonohmic behavior of the samples in the vicinity of a quantum Hall plateau were studied.<>
