    Spectral and Temporal Resolution of THz Detectors based on Quantum Hall Devices with various Geometries

    Quantum Hall (QH) systems can work as very sensitive THz detectors. In this work we report on the spectral and temporal resolution of the QH THz photodetectors with different geometries. The spectral resolutio...

    Time- and Spectrally Resolved THz Photoconductivity in Quantum Hall Devices

    The Terahertz photoconductivity is measured on GaAs/AlGaAs quantum Hall systems. Time resolved investigations show relaxation times form 10 to over 200ns and a dependence on the sample mobility and source-drai...
