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