  text: "We report about the fabrication and analysis of high Q photonic crystal cavities
    with metallic\r\nSchottky-contacts. The structures are based on GaAs n-i membranes
    with an InGaAs quantum well\r\nin the i-region and nanostructured low ohmic metal
    top-gates. They are designed for photocurrent\r\nreadout within the cavity and
    fast electric manipulations. The cavity structures are characterized by\r\nphotoluminescence
    and photocurrent spectroscopy under resonant excitation. We find strong cavity\r\nresonances
    in the photocurrent spectra and surprisingly high Q-factors up to 6500. Temperature
    dependent\r\nphotocurrent measurements in the region between 4.5K and 310K show
    an exponential\r\nenhancement of the photocurrent signal and an external quantum
    efficiency up to 0.26."
